Considering the nature of modern "art" (ex.: "here's a hard drive containing $5M in stolen software!"), and owning a "This T-Shirt is a Munition" (featuring the then-controversial RSA-in-4-lines-PERL code), I'm perversely inclined to find such a "zip bomb" small enough to print the hex or QR code on one business card. The 42kb file is a bit big; any known smaller versions?
