SketchSwap is an online sketching toy, you draw something on the screen and, after submitting, get a random sketch in return. Kinda like File-Swap, but in my opinion, much more fun! And they approve every single sketch submitted before it can be received by others, so you shouldn’t see anything that shouldn’t be seen.
I did a couple of sketch below:
And got these in return. Beautiful!
Endless fun! :D
