Tesselations ?

I can tell, you have no idea what a Tesselation is.  Well a Tesselation is a mathmatical problem with no gaps or overlaps.  It's harder than meets the eye sometimes you just have to do some patterns then you  you find something ,then off you go.  I've done a tesselation before and it was roosters, but it was challenging.  Adios from Bede@Enrich.  : )
