Pumpkin.app places a flickering pumpkin face on your desktop.
You can choose a happy face, sinister face, Apple logo, or a "Happy Halloween" message for the design. Or add an expression of your own to the faces folder by making black and white PICT files. Every place in the picture that is black will show up as a cut out area on the pumpkin. The pumpkin face flickers, or not, by pressing the space bar.
Please read the documentation for more information.
