My first "big" program was a school project submission done in TP. It had an editor for drawing pixels in a (text) grid .. one line at a time. You could draw polygons, name them and the next time you drew something similar to the earlier ones it would recognise it and suggest the same name. If it couldn't find one, it would ask you for a name to remember. Was so much fun writing it. The interface was fun to write. You could use it to tell apart isosceles triangles from equilateral triangles, for example. The machine I used only had two floppy drives and still I recall TP was fast as a Ferrari.
