I've used tcl/tk for quite a while and I now I am quite addicted to it.
I generally develop tcl/tk GUIs for theoretical and computational chemistry. 

Lately I have been using together with VMD (Visual molecular dynamics) program that uses tcl as scripting the main language.

Have a look at some applications I have develop:
