* Logo: [Turtle graphics the LOGO way] - [Turtleshell]
* [Lua]: http://www.inf.puc-rio.br/%7Eroberto/lua.html has a Tk binding. There is also Lux [http://www.equi4.com/lux/README], which makes Tcl callable from Lua.
* ML: sml_tk [http://www.informatik.uni-bremen.de/%7Ecxl/sml_tk/] is a Standard ML package providing an abstract interface to Tcl/Tk
* Modula-3: http://m3.polymtl.ca/m3/pkgf/contrib/m3tcl/.ghindex.html

* [Python]: [Playing Python] and how about a page about tclpython? What about http://www.veritas.com/%7Ebrianw/rivet/ - is there continuing support for this Tk without Tcl project? Also ITCLPYTHON [http://sourceforge.net/project/showfiles.php?group_id=13244&release_id=39973]. The Typcl extension lets you use Tcl from Python [http://www.equi4.com/critlib/typcl.README], it is part of CritLib [http://www.equi4.com/critlib/].

* Scheme: STk seems to be pretty popular - it is a Tk binding for Scheme. Anyone want to talk about it? Or maybe Biglook, a Bigloo Tk distribution? There was some talk about a EuLisp integration of Tcl as well a few years ago. Also there was the REPL Scheme widget library which had Tcl/Tk connections. http://www.colorstudy.com/ianb/projects/tcl-scheme&e=925
