Its a cube 3D perspective illusion using shading and pen! I was going to use it in a game, but that was 2 years ago and I have much surpassed using such old code. Use the x and y slider to move the cube!
Made it 2 years ago. No one ever saw it, now there's a studio present where I can post it! Hooray! I have no Idea why there is a cloud variable. :/
