I didn't mention it, but I really like them. I mean, they're inconvenient, and they make me nervous because for most of my life they were followed by the horrible parts of a migraine, but the scotomas themselves are just so beautiful and interesting that I like them anyway. And in recent years I've been able to enjoy them without so much of the horrible parts afterward.

They certainly are interesting to "watch", but honestly, the first time I've had a scotoma, I was scared I was going blind. I remember thinking whether I'd carelessly looked into a laser at work or something, even though I was sitting at my desk reading Wikipedia when the aura came.
And almost without exception, the visual auras are followed by immense headaches, so I personally would not say I like then very much :D
Is the scotoma similar to the effects that you get by applying pressure to your eyeball?

Or is it quite different?

Pretty different. I used to like to induce pressure phosphenes. I found that a hazard of it was that more pressure produced more spectacular light shows, but that direction led to sore eyes.
