These are actually rather pretty as you may see on that site. I have had such attacks from time to time for at least thirty years, having one today soon after I got home from church. It lasted about twenty minutes. I note on my diary (offline now) that I had one on May 12, 2003, and I don’t think I have had one since. It goes like that. Sometimes I have a few, once an episode starts; we shall see. It’s OK now.
Update November 2007
Corrected the link. Also, look at this animation. Just the way it is.
