Amazing shit.
Any artist that can draw realistic stuff and illusionary work (like those guys who do huge 3D chalk drawings on the sidewalk) are geniuses. Drawing stuff realistic is hard enough, but I don't get how these 3D guys can accurately process in their mind how to draw stuff at angles and then have it show up looking right.
On the other hand, any "artist" that does abstract stuff which my 5 year old niece can similarly fingerpaint on an easel, sorry. No credit from me.
