Hey I have been playing around with adding pictures as a way to add an extra level of fun to the solve.

So far I have just tried stickers and painting but I really want the plastic to be coloured.

As that is out of my reach I was thinking maybe I can get them pad printed on can anyone help out with some advice?

This is my latest attempt.

Finished the last coat of paint last night.

No "piece of cake"
but "piece of art"

That looks really sharp. I would keep up the hand made stuff if I were you.... but there is a place that may be what can help you:

http://speedcubing.hu/webshop/ Olivers Sticker Shop... the forums very own Oliver Nagy.

Oliver printed a bunch of squirrel stickers for my puzzles and I was more than happy with them, check his shop out and see if that is what you are looking for.

Thanks.
I do enjoy painting them myself, but I'll give the stickers a try.

My other thought was have some tiles printed from a colour 3D printer. But I am unfamiliar with how well they can be glued on, any thoughts?
