Ever wonder what to do with all those bottle caps amassed from opening your beer bottles? Well artist John T. Unger has figured out at least one thing to do with them: make beautiful fish art. Talk about taking trash and turning int o treasure. He takes varying used beer bottle crowns and uses them like tiles to make mosaics. Below is just a sample of his work, which can be purchased online, though they are a bit spendy (about $450 per fish). But they are very cool looking.

This fish is made from a mixed palette of blue bottle caps with a white face of Becks caps.

This fish is made from Bud Light, Heineken and Becks bottle caps.

And inspired by Unger’s work with beer bottle crowns, the craft website Instructables has posted step-by-step DIY instructions to make a dragon wall-hanging using 540 beer bottle caps (170 Michelob Amber Bock, 206 Killians, 68 Budweiser Select, 96 Budweiser).

540 crowns is 90 six-packs or 22.5 cases of beer.

And here’s a close-up of the dragon.
