To the aspiring troll, the original locking box had one basic design flaw: once closed, it could be re-opened.

In this version, I have fixed that design flaw, allowing for increased awesome in applications involving high-amplitude, audio-waveform-generation-based lulz.

Alternatively, you can hand it to your *really* clever friends and claim that it's a Japanese puzzle box.

Or waterproof it, put some awesome stuff in it, and bury it in the back yard as a time capsule. Really, the sky's the limit!

I've also added an alternate lid if you would like your box to be a piggy bank. If you want your money back out of it, you'll have to smash it. Just like the good old days!
