Inbox Monitor Applet
I also recorded the
GIMP session for those interested to see how the process looks. Play it
mplayer -fps 30 unless you want to be bored ;).
Note that prior to launching the GIMP I made the sketch on a paper to see if the icon will work. Also I needed to touch up the overpaint at the end, but that didn’t make it into the video.
Update: This perhaps gives the message across better, although is a bit crowded.
