Went to the M. C. Escher exhibition in London today - really, really cool. I actually had just enough topology to get one of his limit-tessellations.

They had some fun interactive things too - see pics (although to my shame I messed up the pose on the "reflection in a shiny ball held by the artist" one, but anyway).

#escher zou dit wel waarderen - een trap van niets naar nergens.

(Je moet toch wat met het oude ijzer en bomen ontzien is ook wel fijn)
