The paint program we used was called "fged". It could generate C code for animations. People would spend hours generating their animation masterpiece, then bring their friends to play it back for them.
I think I remember fged. Wire-frame transformations were popular at that time. There was also IPaint. Spectricon could paint in various graphic modes including 16 colors on the newer Icon computer. The flood fill's hand coded 80186 assembly was still slow due required calls to the Cemcorp graphics API.
