We had a booth at T-DOSE, yesterday and today. I made a bunch of movies, to put them in a playlist and let it run.
Unfortunately, my laptop's videodrivers act rather weird, so xine gives a blue screen to many of the movies, vlc crashes, and mplayer can't properly resize the movies, so it leaves the previous one on the screen. KMplayer does a great job, but I've not been able to get it to just PLAY (let alone loop) the frickin' playlist (WTF is it for?!?). It just stops immediately after each video. Blegh, spend a lot of time on these issues :(
So however useless these video's where, I'm putting a few of them on youtube for your viewing pleasure. Here is the first one, showing off Kalzium.
Edit and another one, KSudoku.
Indeed, the edu apps and the games make for excellent videos ;-)
