[seqfan] Re: floretion video / A108618

[Alonso Del Arte]

Well, Creighton, more people will watch it that way. Only three people
showed up to the screening. It was a worse attendance than my least-attended
string quartet concert, and that was in January at 11 AM with snow and wind
outside. The fault lies with me. I'm so stressed out over my failure to get
a corporate sponsor for the Tiger Stadium memorial concert CD that I barely
advertised this screening. At least the three people in Audience liked your
film, better in fact than the Mandelbrot zooms (which one of them had
already seen before anyway).

Still, I am very grateful that you gave me this opportunity to show it.
