Pencil is an animation/drawing software. It lets you create traditional hand-drawn animation (cartoon) using both bitmap and vector graphics. Animations can be exported as SWF/Flash files.
According to the author, This software was made because there was no other free one like it. So far as I know, I agree. Great intro program for 2d animators and looks it is being actively developed (which would hopefully fix the coordinate problem on the poly line - i just dont use that tool and do fine).
It didn't seem to have any installer, ran right out of the unzipped directory on my WinXP.
