As far as I know, Barry is somewhere around here in the Toronto area. He moved here over a year ago; I heard from him before his actual move, but I haven't heard from him lately.
About the famous ukelele rendition, I think that that was the AIM meeting I missed...the one that Tom probably referred to
I am still AIMing away. It's hard to keep up with all the great ideas on this board, not to mention the advanced mathematics, etc. I thought that Euler's formula had something to do with structural engineering.
Keep up the good work with LD-AIM. It seems that you, and others here, have achieved excellent results with it.
