Well you can definitely take a look at the 2011 Theme Competition thread for some exemplary work. I'm going to forget someone obvious (hopefully others will chime in here too), but here are some other noteworthy themes not included in the contest that stick out in my mind Adultery's MegaMAME Theme is a beauty. Draco1962 is like a theme machine and his work is always very high quality Sins of a Solar Empire is one of my favorites that he did Likewise his Enter the Dragon theme is a pretty sweet minimalistic theme In the WIP department I'm really looking forward to the ConfluenceEx theme being built by Chazz and the MetroEx theme being built by vsilvalopes. And as far as I know Draco1962 is still working on his ode to 1970's prog rock. I guess the answer to including multiple theme presentations in your GameEx demo will depend on your general strategy for these demo movies. If you're also including theme showcases for other front ends, then you should definitely include some good GameEx themes as well. If you're displaying other front ends using only their default themes it might be confusing to show a multitude of themes for GameEx. It also might indicate favoritism for GameEx if you only do this for GameEx. I mean we know that GameEx is your favorite, but one must maintain the appearance of objectivity right? My 2 cents of course.
