These first results were my attempts at making interesting renderings of Celtic interlace patterns. The goal was to have the behavior of the lacework curve gently over their lengths and have a more organic feel than previous tile-based approaches to creating Celtic patterns. This work was done with Eric Stollnitz.

I later attempted to achieve the same goal using traditional Islamic interlace patterns as a starting point. Another page describes the techniques in more details and provides more examples.
