I was playing around with Go's image packages and I made some funky pictures:

$ go run main.go squiggles.go images/squiggles.png 800 600

$ go run main.go swirly.go images/swirly.png 800 600

$ go run main.go tiles.go images/tiles.png 800 600

$ go run main.go xor.go images/xor.png 800 600

$ go run main.go xor_grey.go images/xor_grey.png 800 600
