Pencil is an animation/drawing software that lets you create traditional hand-drawn animation (cartoon) using both bitmap and vector graphics.

Pencil is free and open source. Pencil is not intended to mimick web-oriented vector-based animation software such as Flash. Its main purpose is to make traditional animation.

Neither does it try to rival commercial software targetting the professional animation sector. Pencil is intended to be a simple program enabling anyone to make 2D animation.
