What are some free photostitching programs?

[Heifetz]

My old canon came with a stitching software, but I no longer have the cd. My new nikon d70 doesn't come with anything. Anyone know any free ones that I can use?

thanks

Autostitch is pretty neat.

If you get hugin to actually output anything let me know how the %$^# you did it.
