- 4. A hollow filament as defined in claim 2 wherein said rotatable bodies are electrostatically responsive particles.
- 5. An article of manufacture as defined in claim 2 wherein said liquid contains a thixotropic agent.
- 6. An article of manufacture comprising a transparent material containing at least one vein of transparent liquid, said liquid containing rotatable color-coded micromagnets dispersed therein.
- 7. An article of manufacture as defined in claim 6 wherein said transparent material is an extruded polymeric material.
- 8. A product comprising a substrate and an article of manufacture as defined in claim 7.
- 9. A method of displaying an image which comprises imagewise selectively rotating the color-coded micromagnets in an article of manufacture as defined in claim 6.
- 10. A method as defined in claim 9 wherein said micromagnets are rotated by the magnetic field of an electric current.
- 11. A product comprising a substrate and an article of manufacture as defined in claim 6.
- 12. An article of manufacture as defined in claim 6 wherein said liquid contains a thixotropic agent.
- 13. An article of manufacture as defined in claim 6 wherein said liquid comprises an oil.
- 14. An article of manufacture as defined in claim 6 wherein said liquid comprises a hydrophilic liquid.
- 15. A method of producing an article of manufacture as defined in claim 10 which comprises extruding said transparent material through a die having at least two outlet orifices positioned therein and passing said transparent liquid through said orifices simultaneously with said extrusion.
- 16. An article of manufacture comprising a transparent material containing at least one vein of transparent liquid, said liquid containing rotatable bodies dispersed therein, which bodies are capable of being selectively oriented to produce a visual display.
- 17. An article of manufacture as defined in claim 16 wherein said transparent material is an extruded polymeric material.
- 18. A product comprising a substrate and an article of manufacture as defined in claim 17.
- 19. A method of displaying an image which comprises imagewise selectively rotating the rotatable bodies in an article of manufacture as defined in claim 16.
- 20. A method as defined in claim 19 wherein said bodies are rotated by the magnetic field of an electric current.
- 21. A product comprising a substrate and an article of manufacutre as defined in claim 16.
- 22. An article of manufacture as defined in claim 16 wherein said rotatable bodies are magnetically responsive particles.
- 23. An article of manufacture as defined in claim 16 wherein said rotatable bodies are electrostatically responsive particles.
- 24. A method of producing an article of manufacture as defined in claim 16 which comprises extruding said transparent material through a die having at least two outlet orifices positioned therein and passing said transparent liquid through said orifices simultaneously with said extrusion.
- 25. A method of displaying an image which comprises imagewise selectively rotating the color-coded micromagnets in a fabric comprising hollow transparent filaments bound together, said filaments containing a transparent liquid having rotatable color-coded micromagnets dispersed therein.
- 26. A method as defined in claim 25 wherein said micromagnets are rotated by the magnetic field of an electric current.
- 27. A method of displaying an image which comprises imagewise selectively rotating the rotatable bodies in a fabric comprising hollow transparent filaments bound together, said filaments containing a transparent liquid having rotatable bodies dispersed therein, which bodies are capable of being selectively oriented to produce a visual display.
- 28. A method as defined in claim 27 wherein said bodies are rotated by the magnetic field of an electric current.
