em, oh. This was interesting. Seems likes it's all speculative, from looking at the website, but it might be interesting to see. I've always wondered if they'd ever find evidence of dragons existing. And of course, I've had my own thoughts. (Like how dragons may be built out of light cartilage or something that would easily disintegrate, and if they were even vaguely intelligent creatures, they may have had some sort of death ritual, like say burning the corpse to ash, if they could breath fire or such.)
The wikipedia has this to say about cave paintings though: "The paintings were drawn with red and yellow ochre, hematite, manganese oxide and charcoal." This is useful for those of us who may want to make use of such decorating techniques. (^*^)
Wikipedia also has this to say about the Nazca line drawings in Peru: "The Lines were made by removing the iron-oxide coated pebbles which cover the surface of the desert. When the gravel is removed, they contrast with the light color underneath. In this way the lines were drawn as furrows of a lighter color." It interests me that such a simple thing has lasted for around 1400 to 2200 years.. even in the desert, it rains, and climates change over the millennia. I think they showed that it was possible the Nazca could have made crude balloons with which they could observe the line drawings..
There have been some plottings in the works for workshops at this year's WTT.. hard to say what exactly. Nothing's yet concrete.. but the main one seems like it'll be something of a discussion about perceptions altering over the course of time, what sort of things we've experienced these past years, minor discussions of different topics that have become over interest in this time, and the serving of Glop.
Possible other workshops: Shape shifting (by mmsword), Cybernetics (by me), and Calendars & Culture (by me and helen99). (I've never done a workshop, though, so who knows what'll happen..)
