Fooly-Coooly, also known as FLCL.  
All six episodes of this 6 episode OVA

All are in .OGM format
they have both the English dubbed and Japanese original audio tracks embedded in each file
English subtitles, or directors commentary

If you don't know how to play the format, i suggest Zoom Player

I use the Zoom Player Home MAX.  It's free, sleek and has every codec on the face of the planet.  

PLEASE SEED!!!!
