Features:
Simple Interface:
- A number of useful drawing tools are made available. (See Drawing Tools, below.)
- The drawing canvas is a fixed size, so the user doesn't need to worry about 'pixels' or 'inches' when making a new picture.
- The entire program fits on a screen as small as 640x480, and can be displayed full-screen, to hide the computer's underlying 'desktop' interface. (It defaults to 800x600 mode, but can run at larger sizes and in portrait or landscape mode, as well.)
- Loading and saving of images is done using thumbnails, so no knowledge of the underlying operating system's filesystem structure is needed. Even filenames are unnecessary.

Entertaining Interface:
- Fun sound effects are played when tools are selected and used.
- A cartoon version of Tux, the Linux penguin, appears at the bottom to give tips, hints and information.
