Create a experiment with dots appearing random on a screen

[nyu.nirs at gmail.com]

I appreciate the help and as much as it is frustrating, it is, as you
say, a learning experience and I'll be damned if I don't figure it
out :)

I'll try to post when I eventually figure it out.

Thanks again,

Fredrik
