A small description of each would be nice, since it's a hassle searching everything on my google search engine.
*Tengen Toppa Gurren Lagann: Two guys from an underground village use a mini-mecha they found buried in the earth to fight back against a tyrannical ruler that wants to keep human beings trapped underground. Spirals out from there, though.
*Legend of the Legendary Heroes: A man with a demon's eye that sometimes takes control of him and wields terrifying amounts of power is charged by the king, an old friend from military academy, to search for relics of a fabled group of heroes that once saved the world from an invasion of dark powers.
*The Irresponsible Captain Tylor: A man who's only redeeming quality seems to be absurd amounts of luck is put in command of the most dysfunctional ship crew in the fleet.
*Dead Leaves: Two amnesiacs are thrown into a super high security prison on the moon and begin trying to escape
*Brave King GaoGaiGar: A cross between Transformers and Power Rangers, pretty much.
*Demonbane: Cthulu mythos combined with giant robots.
*Kodomo no Jikan: First time teacher has to deal with a student's crush on him, unfortunately the student is very mature for her age and devious to boot. Don't worry, it in no way promotes pedophilia.
*Bokurano: a group of kids are tasked to protect earth from invading enemies with a giant robot. The catch: If they lose, earth is destroyed, but if they win, the pilot for that battle dies.
*FLCL/Fooley Cooley: Robots sprouting from a kid's head, and a strange lady on a vespa that fights with a guitar. It's hard to explain, but it's still pretty good XP
*Macademi Wasshoi: Hilarious comedy about a boy at a wizard's academy who accidentally summons a mysterious little girl during a botched summoning exam. More about the characters than the magic, though the magic allows for very odd circumstances to arise on a regular basis.
*Abenobashi: two kids travel to parody versions of their home city, covering a wide range of genres, from giant robots, to dinosaurs, to american movies.
Very short descriptions, but hopefully they give you a good enough idea of what to expect. If you want more info, try looking them up on Wikipedia or TVtropes.
