I'm proud to announce SqueakJS, a new Squeak VM that runs on Javascript:
http://bertfreudenberg.github.io/SqueakJS/
It was inspired by Dan's JSqueak/Potato VM for Java, and similarly only runs the old Squeak 2.2 mini.image for now. But I developed it inside the Lively Kernel, which allowed me to make a nice UI to look inside the VM (in addition to all the Lively tools):
I don't know if anyone commented on the UI, but I love the VM debugger panels that display and control the running VM while you use the Squeak mini image running right next to it.

Thanks :) And there's even some stuff that's not exposed in the UI yet. I use the Lively tools to inspect the VM. Then for example
this.breakOnNewMethod = true;
will break when the newest CompiledMethod is executed - which is your next doit.
Or, use the Chrome debugger to step through the GC:
debugger; this.image.fullGC();
It's fun - for our sort of folks, anyway ;)
