there is so much bullshit apps and especially games out there. here are three that look promising:

eBoy's FixPix
Assemble 150 eBoy artworks by tilting your mobile

Zen Bound 2

Become an object-bondage master...

Auditorium
Pratice composing by bending light rays

I'am sure there is more out there - if you know any more: comments are welcome!
