I've got my pet projects:
   * multiplatform embeddable multithreaded application web server in Tcl
   * full bindings in Tcl for DDEML (Dynamic Data Exchange Management Library - MS Windows IPC used in many SCADAs)
   * Tcl/tk framework for building database/form-based application a'la Borland Delphi
   * enhancement to starkit/starpack deployment for multithreaded application
and a few others.
