JSqueak

Dan Ingalls has released JSqueak, a Squeak interpreter written in Java. It's roughly 5000 lines of Java. The download includes a Smalltalk image. Running JSqueak with this image on my MBP felt like déjà vu. It reminded me of learning Apple Smalltalk on my ancient Macintosh Plus.

Note: The Apple Smalltalk screenshots in the link are actually running in Mini vMac on a Macintosh. That's a 68k emulator running an interpreted language inside a virtual Mac running on an Intel Mac. Aren't VMs cool?
