Hello,

Before I knew Bitcoin, i was inspired by binairy art, but in 2011 i've came up with this:

It's a spiral of the binary numbers 1 t'ill 1101100 or in normal numbers, counting from 1 t'ill 108.
Now when you reach number 1101100 (108) it closes itself, when the last 0 (zero) blocks all the 1's inside of it... Actually, it's a nice digital safe, just like Bitcoin... Only never discovered.

Thanks.
