Circus World Flash

Another flash (or image impulse) the other day, while working out. It lasted about 5-6 seconds, and was of an open area just inside the entrance of what once was Ringling Brothers Barnum and Baily Circus World near Orlando. This park has long since closed, but I did go there a few times as a kid. In the flash I could see the area just outside a very large auditorium that was made to look like a giant tent.

This project elicits some of the feel of an image impulse...

What Triggers Image Impulses?

I'm not sure what to call them, but I sometimes have random and vivid visual memories of particular locations, most of which appear to be completely unrelated to my current experience. I could be standing in the kitchen, riding in the car, or taking a shower. Actually, it does seem that these image impulses occur most frequently when I'm in some sort of half-resting state. Other than that, they seem to be completely unpredictable in terms of timing and content. They typically don't include any significant set of events, and last for somewhere between 5 to 10 seconds. Their most memorable feature is the location/landscape itself.

What is Visual Memory?

A cross between photographic memory and spatial memory?
