For this project, the client wanted to see different mosaic options, irregular shapes and random colors. Instead of using the traditional photoshop approach, I have decided to test Railclone inside 3D Studio Max and see what type of results I can achieve. The beauty of using Railclone is that once you have made your initial setup it, its pretty easy to extend the mosaic to almost any surface using splines.
Hope that was helpful to some!
