Some of the removals were geometric patterns that I had used for mazes. Although they have made good mazes, they showed nothing special as far as tessellations are concerned. These first two illustrated isohedral class IH71, a special case of C4C4C4C4 with all edges the same and symmetry over one of the diagonals. I have no shortage of other examples.
The head and wings of this stylized bird are OK, but the tail end is all wrong. With the addition of some better illustrations, it was expendable.
These crude cups of type TTTTTT were used in a maze book. They are not very interesting or attractive.
dolphin tessellation by Andrew Crompton. If I had discovered it independently I would have kept it, but I did not.
(Looking for a link to IH29, I found that a site that I have relied on as a reference, http://freespace.virgin.net/tom.mclean/index.html, is no longer responding. There is a mirror, however, at http://www.jaapsch.net/tilings/mclean/index.html.)
