Eclipse just keeps amazing me.
A couple of days ago I stumbled across a project called Zest. Zest is a set of visualization components and graph layouting algorithms. I'll have to check it out one of these days because the screenshots look really cool and it might come in handy one day.
Looking back, Chris Aniszczyk blogged about Zest a couple of months ago. I'm pretty sure I have seen his post pass by on the Planet but it must have slipped my mind back then.
I wonder how many other cool Eclipse projects exist that I, and most other people, don't know about.
