The invention claimed is: 1. A process for the manufacturing of a decorative surface element, where the appearance of the decorative surface changes with angle of view of the surface element, which element comprises a substrate comprising a fiber board, said board further comprising fibers on an upper surface of the board, an upper decorative surface over said upper surface of the board and a protective upper wear layer of lacquer over the decorative surface, wherein the process comprises the steps: a) providing a substrate of a fiber board; the board further comprising an upper surface of fibers of the board; b) orienting the fibers of the upper surface of the board in a predetermined pattern by applying a liquid solvent on top of the upper surface of the board causing the fibers of the upper surface of the board, where the solvent is applied, to rise from the board, c) applying pigment on the upper surface of the board to form the decorative surface, and d) applying an upper protective wear layer of lacquer on the upper surface of the decorative surface. 2. A process according to claim 1, the liquid solvent is applied in a predetermined pattern. 3. A process according to claim 2, wherein the liquid solvent is applied by means of a surface structured calendar roller. 4. A process according to claim 1, wherein the liquid solvent is water. 5. A process according to claim 1 wherein a lacquer comprising pigments is applied on the upper surface. 6. A process according to claim 5, wherein the pigmented lacquer is applied by means of airbrushing. 7. A process according to claim 6, wherein the pigmented lacquer is applied at an angle of 5-80° from the upper surface. 8. A process according to claim 5, wherein the pigmented lacquer is applied in two or more steps and two or more colors are used. 9. A process according to claim 8, wherein the pigmented lacquer is applied by means of airbrushing and that at least one color is applied from a direction deviating from the direction of which the other color or colors is applied. 10. A process according to claim 1, wherein the wear layer further comprises at least one layer of overlay paper impregnated with melamine formaldehyde resin. 11. A process according to claim 10, wherein the wear layer further comprises hard particles with an average particle size in the range 50 nm-150μm. 12. A process according to claim 11, wherein the hard particles are selected from the group consisting of particles of at least one of silicon oxide, aluminum oxide and silicon carbide. 13. A process according to claim 10, wherein the wear layer further comprises a semi-translucent pigment. 14. A process according to claim 10, wherein the wear layer further comprises a printed decor. 15. A process according to claim 14, wherein the printed decor is opaque, covering only parts of the surface of the wear layer. 16. A process according to claim 1 wherein the substrate consists of fiber board.
