Five minutes on Shape Morphing
The Web supports this cool image format called SVG
It's vector graphics on the web!
You can animate stuff on the web. Here I'm animating position and color.
Slightly less known fact:
you can animate shapes too!
You know it's cool because YouTube does it.
(But really, it can be cool for increasing understanding of what's happening in a user interface. Instant change = hey what happened! Morphed change = people see exactly what happened.)
Go forth and morph!
