Geometry Puzzle

I honestly don't know what category this goes in... Try, if you dare, to figure out the next number in the sequence. Hint: Only TIME will tell- thus why I drew it on there. This took me forever to draw, I was drawing it during math- our teacher gave us that puzzle and we didn't even get the Time hint! I call it a geometry puzzle because that's what class we were in when he gave us this puzzle. Have fun.
