I first downloaded squeak last summer (1999) and then got busy with school and work and such and let it lapse, recently though (2000-02), I've been drawn back to it because of it's power grace and simplicity.
Unfortunately I'm not able to fully enjoy the Morphic interface due to old and pokey hardware, so most of my experimentation has been on the mini.image intended for PDA's.
I'm interested in Simulations and possibly re=implementing the swarm library classes in squeak.
I maintain (?) a website at [swirlyhead.com] where I will probably start a squeak node. Dead Link 2003-12-27
