I would be happy to self-pimp for this cause as well! All can be found at http://www.hamumu.com :
Dr. Lunatic Supreme With Cheese - the one and only. Odd, perhaps.
Loonyland - A Zelda-ish cartoon action-RPG
Loonyland 2 - A cross between Zelda, Diablo, and WoW (without all that internet nonsense). And Garfield. With guys in bunny suits!
etc.
And our mini-games, which are certainly fitting the desire for experimental weirdness (the above are certainly exceedingly weird stylistically of course, but that's just how I am):
Moon Invaders - quickie little game, very different take on Tower Defense
NPC Quest - an RPG you don't actually play, but there is skill involved unlike Progress Quest
Ninja Academy - a ninja platformer controlled by a single button... but with like 10 different moves anyway!
Still Pond - art, man, it's art.
Two Roads - also art... maybe?!
Hitsuji, Ninja Kitty, Medusa's Lament.. etc. Good stuff you should experience once in your life.
And a shout-out to a phenomenon that I am only a small part of: http://www.towlr.com - destroy your mind with the power of Towlr. Seriously, not to be missed, by anyone.
+ Towlr may frustrate you. This is normal. +
