Thanks for the kind words, everyone - this brings back a lot of memories for me too. You know, I wrote everything in that book either late at night or on weekends, and I never really knew if it much mattered to anyone (feedback was a lot harder to come by in pre-Internet days); reading these comments goes a long way to making all that work worthwhile.

Oh, and laichzeit0 - my apologies to your dad for the weight of the book. There have been a few times when I was lugging one around and wishing I had been more sparing with the words :)

The effect happens in a real room with a strobe light going, but that's the same phenonemon - low persistence. It also happens in other virtual settings with lower contrast and brighter overall illumination (although it's less pronounced), so it's not just a matter of a dark environment and bright lines. It doesn't happen in the exact same virtual Tron-like room if persistence is set to full, and it's reduced at half persistence. So it does appear to be an artifact of low persistence.
