Yeah, consider these clips works in progress. Hopefully we won't have to rely on YouTube in the long run; instead we can embed our own vids on the site, and that should allow for better resolution/framerate videos.
About the Invisible Hand map...yeah, I know what you mean about the dark models and everything. It looks fine at the original video size, but after uploading to YouTube it looks like crap. Fortunately I made replacement videos for those hard-to-see clips (the kick clip, especially), so they should be replaced shortly...after I get back from work.
A film extra would be awesome, but for that I'd need to get on a server...and the way things are with my current DSL connection, I don't know if I'd get any lag-free recordings.
PMing you contact info, chief.
