Rubiks creation

This are some old snapshots from my render long ago. just want to share. There was no tools to automate the creation of this blocks. I need to manually duplicate series of rows and rows of smaller cubes . As well as assigning colors , I have to create each shader for them. These type of color set were very hot during those days pastel soft candy like comfortable looking shades and hue. In the end I leave the grey colored blocks to show 3 different space in 3d axis.
