Ok, I know what you're thinking. 

p0ss finally lost it, and submitted a cube.

Well my friend, this no ordinary cube. for you see it has a texture, a texture which tiles in every direction. This allows for rapid prototype development and the creation of placeholder elements, because as soon as you put two of these cubes together, you can't even tell they were ever apart.  and if you put four of them together you end up with a giant cube that is still seamless.

So this block, is anything your mind can imagine, it is a wall, a set of stairs, a stage, a pole, anything.  its like minecraft,  if minecraft had only one super tiling block.

In all seriousness I figured this would be quite useful for game developer who is testing out their engine and needs to create some walls or buildings quickly.
