I won't look at the videos, but the static images are neat to look at.

Liz the Squeak, that's an interesting childhood visual memory. Brings to mind two items.

First, the intricate colourful weave and embroidered or appliqued patterns made by South American native peoples have been tentatively identified as stemming from hallucinogenic(sp?) visions, either from use of various plant drugs or from edge of sleep visions.

Second, and entirely personal: when we were little (under five), my mother played guitar and sang to put us to sleep. I used to 'see' the guitar notes as little floating three dimensional, round cornered triangles with round dents in their centres, in soft dark colours. Typically, there would be two or three colours shading into one another from the outside into the centre. It's a vivid memory.
