Last nite Sen & Sonja and her two boys hosted a solon gathering in the apartment, about 12 folks showed up from Leiden, Rotterdam and Amsterdam... they showed slides on a sheet in the window, and on the ceiling. Her two sons did some music on piano and violin, a colleague from Rotterdam did a rap in both Dutch and English. I took the opportunity to do a dry run of my presention for the Technion Ethnomath meeting.
It was great fun, food and good people.
These fotos were taken right now (about 9am), needless to say I am not going out quite yet...
We might go to Amsterdam tomorrow... Sonja says its easy... woo hoo!
