April Ampersand 15

I think that punched tin can sometimes look sort of awesome, so I decided to give it a try. I started simple.

And here's how it looks in the magical twinkle of candlelight.

This was fun. I read somewhere once that the trick is to fill the can with water and then freeze it so that you don't bend the can with every hole you punch into it. That worked like a dream, except that the ice made the bottom of the can bow out when it expanded as it froze. Anybody know how to solve that problem in the future?
