Tux Paint is easy to use, includes countless fun effects, and provides many configuration options.

• Multi-Platform.
• Simple Interface.
• Entertaining Interface.
• Drawing Tools.

Other Features are below:

• A number of useful drawing tools are made available

• 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.

• Images can be exported from Tux Paint (e.g., to your “Pictures” folder).

• 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.
