Best/favorite indie games?

I find myself on yet another indie game binge, so I got to wondering what are everyone else's favorite indie games/indie games they think are best?

My personal favorite is Thomas was Alone, or Deadly Premonition if you have a looser definition of indie.

Some other I would recommend would be Antichamber, Botanicula, Cave Story+, or if you wana get really weird Starseed Pilgrim

i'm playing Super Meat Boy at the moment. it's fun and fast paced.

Kerbal SPACE Program.

Bastion, and Transistor.

Trine 2. KSP, and Fez

Uf thats hard. I enjoyd Machinarium A LOT. But KSP is also very very nice. I think it would be one of the both.
