STk is a free R4RS Scheme interpreter which can access the Tk graphical package. Concretely, it can be seen as the standard Tk package where Tcl has been replaced by a Scheme interpreter. STk embeds also an efficient CLOS like object oriented system, called STklos, which provides:

• multiple inheritance,
• generic functions,
• multi-methods,
• a MOP (Meta Object Protocol)
