Ideogramic ApS develops diagramming tools that are especially tuned for use on electronic whiteboards and that are operated using gestures much like on a [Palm Pilot].

Major parts of the applications are implemented in Tcl/Tk.

More information can be found on Ideogramic's homepage: [http://www.ideogramic.com].  A
profile of Ideogramic's work appears in the on-line article, "Programming
[UML] in Tcl" [http://www-106.ibm.com/developerworks/webservices/library/ws-xtcl.html].
