I included 100% clones in the title as a joke (since most people say 100% Pen if it's pen :P And most projects that looks similar to this is pen..) Hover your mouse to collect bubbles. Once you collect as many bubbles as you wish, you can 'release' them by dragging your mouse away. Have fun! (If you reload the page, it's really fun to put your mouse in the middle and click the green flag on screen. Then you can gather ALL the bubbles right away ^.^)
