Squeak is an implementation of the Smalltalk system with some very outstanding

Squeak Home Page, and some more at the CREATE
- It is free!
- Its bytecode interpreter is almost completely written in Smalltalk,
which is then translated to C. Sources for the interpreter and the
translator are available in the system.
- It has a very active developer community, including some of the original
inventors and implementors of Smalltalk-80.
- It is available on a number of platforms, including Mac (original
implementation), Windows NT/95, various Unixes, Acorn Risc PC.

Squeak has an active mailing list. To subscribe to the list, send a mail
with the word subscribe in it. The list is archived at the UIUC
Mailing List Archives (note that the archive is quite unwieldy; probably
someone would like to make it more accessible?).
Thing's I'm working on in my little spare time:
- Morphic Plumbin'! An extension of
Ward Cunningham's Plumbin'
to run within Morphic. I think it's immensely cool :-)
Excerpt from the change set header:
This changeset converts the original Plumbin' for Squeak into
a Morphic version.
You need to load all three Plumbin' files because 2 methods for PressureTank
are added. A new kind of Tile (BrokenElbowTile) is implemented to
break cycles. It displays itself with a gray overlay, and has a menu
item to 'fix' it (convert back to ElbowTile).
To start, execute 'Tile exampleMorphic'
- Creating stand-alone executables with Squeak. Look here
for an explanation and usable code for the Macintosh (PowerPC platforms
only at the moment).
- 3-D rendering entirely done within squeak. Come back soon to see
examples of output (you'll have to wait a little longer for code).
- I've got Squeak changed to 2 bit tags, opening up the possibilities
for more immediate classes. Look at 2tagbits
for the code (squeak 1.18)!
- Dynamic Primitives - a mechanism for specifying primitives in Smalltalk
(which Squeak already does) and translating them into native code
completely from within Squeak, without invoking an external C compiler
