I'll be teaching a film class in London this summer and I'm wondering--will I be able to play my American DVDs on English DVD players? Since I suspect the answer is no, will it work if I play them through my IBM laptop and plug this into an English computer projector? Or will I simply have to buy all new DVDs in the English standard?

Mapmaking: I want to make my own globe. Does anyone know of any software or method (for winXP, cheaper/free is better) that will take an image of the map (ie cylindrical projection), and turn it into a paper template ready to print, cut, and stick onto a sphere - BUT - preferably one that is centred on the poles, like commercially-made globes, rather than the (much less effective) strips centred on the equator. Failing that, anything that works :) [more inside]

I often walk past artists painting/airbrushing photorealistic billboards on the sides of buildings. Talent aside, how do they do this? I would imagine that an original image would be projected onto the building, and then traced, but how do they avoid image distortion if the environment doesn't allow for a perfect straight-on projection? Do they project an already-distorted original onto the wall?
