Ok some of my cartoons my be tangental or obtuse. This ones is just a round of two dimensional, bad quality geometry puns. A total sin cos' there is no real focal point to transverse this from this null set of ideas into a more solid sphere of humour. Truely this line is not my area. My translation of these notions looses something from their original magnitude, & is left un-paralelled & looking a little plane. My apologies.
