Like most old school hackers, I try to explore ideas that keep me awake ... the "I wonder if I can make an x" where x may be a topological manifold, an arduino line-follower, a garden leaf moulded into ceramic, a Penrose tile pattern, an LTE geolocation algorithm...
And, as most of you realize, this Klein bottle microbusiness is mainly to have fun and stay busy -- a chance to fool with everything from math to glassblowing.
Best part, of course, is meeting math folk, students, computer jocks, and random visitors. To each, I hope, I leave the strong encouragement to keep exploring!
My warm wishes to each of you, on a sunny Sunday morning in Oakland, California!
