This post is from one of several previous incarnations of this site and probably doesn’t quite fit the current format. In a former life this was a group blog and a tumblelog before it became a static jekyll site. If anything looks broken or is worded oddly that could be why. Pardon the dust.
I’d presumed the fullscreen mode on most video sites was a chromeless window spawned by Javascript. Apparently it’s native functionality in the more recent Flash players.
