We've seen the insanely complicated things people can do with paper by painstakingly folding it (Matthew Shlian) or cutting it by hand (Bianca Chang). It was just a matter of time before another OCD paper artist/engineer got his hands on a laser cutter and made things really complicated.
Artist Eric Standley, a SCAD grad and now associate professor at SVA's Virginia Tech branch, painstakingly assembles hundreds of sheets of differently-colored laser-cut paper. The intricate shapes evoke stained glass windows or something you would carve if you were imprisoned for 30 years. This man has the focus and patience of a sniper on Adderall.
