Effects Suggestions

I need to apply a mosaic effect to a comp. I need to zoom right in and see individual tiles, with some sort of 3D effect to the edges of each one...

Anyone got any tips on how to do this? Obviously a simple mosaic effect is not going to cut it as I need to be able to apply some sort of bevel to the edge of each square-- a combination of effects is required. I'm sure there must be some way to do this relatively easily....

Ideas??

Thanks in advance.
