YouTube user and Rubik's Cube expert Kyudan2 has been quietly busting out these incredibly impressive works of puzzle art for months now. Up until now, his focus has mainly been in recreating Pokemon sprites, like the simple Ash and Pikachu from Pokemon Yellow...
... to more complex Pocket Monsters such as Togepi, rendered here in 99 cubes.
Amazing work. Kyudan2 has more in his YouTube channel, and plans new vids on a regular basis, so go subscribe the living heck out of him.
