Looks great! The biggest drops sort of spoil the illusion at times because they pass in front of or behind other drops without absorbing them. Maybe a cool tweak for v2 would be to add some simple collision resolution?<p>It would probably look great if you did a front to back sort based on droplet size, and resolved collisions (which you'd have to detect) by deleting the smaller droplet.
I'm finally getting pretty comfortable with Rails, HTML, CSS, enough to actually use things like this. Can anyone recommend slick/good looking js like this that would be fun to toy with?
