There is a separate gaming piece called the Ruby Cube. See the link:

Description:
Yes, more Rubik's-related design, this time the Ruby Cube, designed by J.P. Meulendijks.
It's a side table, made of MDF and special acrylic plates - all the same colour, but rather cleverly changing colour depending on the angle it's viewed from. So you always get the chequered effect wherever you are in the room.
It retails for $399 (around £200). Delivery is included for US and Canada, rest of world delivery is available, email them for price.
