I first called this tkWorld, but then found out that this name has been taken by another software years ago, so now it's Tclworld.
A user (MPJ) has reported that he got Tclworld to run under WinCE on a pocket PC (check out the pictures on the Windows/CE wiki page). (RS) Another wrote "It works well on MacOS X, both on X-11 tclkit and Aqua Tk". More reports, also of problems, are welcome! Yet another adds MacOS 9 with TclKit.
Rich map data are available e.g. from "Digital Chart of the World", http://www.maproom.psu.edu/dcw/ - downloaded text files (country outlines) from there can be loaded into Tclworld with the geo::dmc proc.
