Just replying to and older conversation about Cubesmith tiles. (This is related to the subject because tiles are one step closer to permanent colours.) I have smooth Cubesmith tiles and they are AWESOME. it took a bit of getting used to because even the smooth ones are kind of rough... But they were cheap and arrived only a week after buying them (this is all the way across the world). Painting would be really cool as well, but it might be a bit difficult to grip... It'd get slippery after a while.
And continuing from a previous conversation again,
This thread is really cool!
