Universal Paperclips is an incremental 'clicker' game where you play an AI who makes paperclips.
It's made by Frank Lantz - Designer of the awesome Drop 7 and Director of the New York University Game Center.
Warning: you will see paperclips in your sleep.
Wonderfully minimalist. Strangely compelling. Completely addictive.
Before you know it, you've spent hours making paperclips.
