Recommend any good homebrew software for the new nintendo 3ds??

i think its called GBA something. it makes your LEDs flash rainbow colors
CTGP-7 if you have a game cart of mario kart 7.
This technically isn't homebrew, per se, but if you have hShop, PictoChat is available on there, and to my knowledge it's the one thing a DSi can do that a 3DS can't do.
