1. A mounting assembly for use in mounting a video display terminal on a load supporting surface comprising: a. a top member for receiving thereon said video display terminal, b. a base assembly for engaging said load supporting surface, and c. an intermediate block assembly disposed between said top member and said base assembly, said intermediate block assembly including: i. a bridge housing fixedly attached to said base assembly, ii. a first rocker fixedly attached to said top member and seated for rocking movement on said bridge housing, iii. a lever arm pivotally coupled at an intermediate location along its length to said bridge housing and pivotally coupled at one end to said first rocker, and iv. a second rocker fixedly attached to the top member and seated for rocking movement on the bridge housing, d. whereby pivotal movement of said lever arm will cause a corresponding tilting of said top member relative to said base assembly, e. wherein said intermediate block assembly further includes a thumbwheel rotatably mounted on said bridge housing and pivotally attached to the other end of said lever arm, whereby rotation of said thumbwheel will cause a pivoting movement of said lever arm. 2. The mounting assembly of claim 1 and further including means for securing said first and second rockers to said bridge housing. 3. The mounting assembly of claim 2 and wherein said bridge housing includes a pair of spaced apart transverse slots and said rockers are seated in said slots. 4. The mounting assembly of claim 3 and wherein said base assembly includes: a. a top plate fixedly attached to said bridge housing, b. a bottom plate below said top plate, and c. a bearing disposed between said top plate and said bottom plate and connected to said top plate and said bottom plate for enabling rotational movement of said top plate relative to said bottom plate, d. whereby rotational movement of said top plate relative to said bottom plate will produce rotational movement of said top member relative to said load supporting surface. 5. The mounting assembly of claim 4 and further including roller means disposed between said rockers and said bridge housing for supporting said rockers in said bridge housing and enabling smooth rocking movement of said rockers relative to said bridge housing. 6. The mounting assembly of claim 5 and further including bumper means mounted on said upper plate of said base assembly and extending downward and in contact with said bottom plate of said base assembly for distributing the load carried by the upper plate over the bottom plate. 7. The mounting assembly of claim 6 and wherein said thumbwheel includes a spiral groove on one surface and said intermediate block assembly further includes an actuator pin extending through a hole in said lever arm and riding in said spiral groove. 8. The mounting assembly of claim 7 and wherein said first rocker is a crescent shaped member having a flat top surface and an arcuate bottom surface. 9. The mounting assembly of claim 8 and wherein said first rocker includes a groove on its bottom surface and said intermediate block assembly includes a knuckle rotably mounted in said groove for coupling said first rocker to said lever arm. 10. The mounting assembly of claim 9 and wherein said bridge housing is a unitary structure made of plastic. 11. A mounting assembly for use in supporting a video display monitor on a load supporting surface comprising: a. a top member for receiving thereon said video display monitor, b. a base assembly for engaging said load supporting surface, and c. an intermediate block assembly disposed between said table top and said base assembly said intermediate block assembly including: i. a bridge housing fixedly attached to said base assembly, ii. a first crescent shaped rocker seated on said bridge housing for rocking movement thereon and fixedly attached to said top member, iii. a second crescent shaped rocker seated on said bridge housing for rocking movement thereon in spaced apart relationship from said first rocker and fixedly attached to said top member, iv. a lever arm attached at one end to said first rocker and pivotally attached at an intermediate location along its length to said bridge housing, said intermediate location defining the fulcrum of said lever arm, v. a thumbwheel rotatably mounted on said bridge housing and coupled to the other end of the lever arm, whereby, rotation of said thumbwheel will cause pivotal movement of said lever arm, vi. whereby, pivotal movement of said lever arm about its fulcrum will cause rocking movement of said rockers about and relative to said bridge housing producing thereby a tilting movement of said top member relative to said base assembly. 12. The mounting assembly of claim 11 and further including means for securing said rockers to said bridge housing without limiting rocking movement of said rockers relative to said bridge housing. 13. The mounting assembly of claim 12 and wherein said base assembly includes: a. a top plate said top plate being attached to said bridge housing, b. a bottom plate said bottom plate being adapted to seat on said load supporting surface, and c. a bearing disposed between said top plate and said bottom plate and connected to said top plate and said bottom plate, and d. whereby rotational movement of said top plate relative to said bottom plate will produce rotational movement of said top member relative to said load supporting surface. 14. The portable table of claim 13 and further including roller means for supporting said rockers in said bridge housing enabling smooth rotational movement of said rockers relative to said bridge housing. 15. A tiltable mounting assembly comprising: a. a top member, b. a base assembly, c. an intermediate assembly disposed between said top member and said base assembly, d. said intermediate assembly including: i. a bridge housing, ii. a first rocker seated on said bridge housing for rocking movement relative to said bridge housing and fixedly attached to said top member, and iii. a second rocker seated on said bridge housing for rocking movement relative to said bridge housing and fixedly attached to said top member, and e. means for rocking said first rocker relative to the bridge housing whereby said rocking will cause tilting movement of said top member relative to said base assembly, said means for rocking comprising a lever arm coupled to said first rocker and to said bridge housing, and rotatable means including a thumbwheel coupled to said lever arm and adapted and configured so that rotation thereof will cause a movement of said lever arm and thereby rocking of said first rocker. 16. A tiltable mounting assembly comprising: a. a top member, b. a base assembly, c. an intermediate assembly disposed between said top member and said base assembly, d. said intermediate assembly including: i. a bridge housing, ii. a first rocker seated on said bridge housing for rocking movement relative to said bridge housing and fixedly attached to said top member, said first rocker including a groove on its bottom surface, iii. a lever arm pivotally coupled to said bridge housing, and iv. a knuckle rotatably mounted in said groove for coupling the first rocker to said lever arm, and e. means for rocking said first rocker relative to the bridge housing whereby said rocking will cause tilting movement of said top member relative to said base assembly. 17. The tiltable mounting assembly of claim 16 wherein the means for rocking includes a thumbwheel rotatably mounted on said bridge housing and coupled to the level arm, whereby rotation of the thumbwheel will cause pivotal movement of said level arm and thereby will rock said first rocker.
