xmailbox

xmailbox: A version of xbiff with animation and sound effects. It displays an icon, which changes when mail comes in. Normally this involves checking the size of a file, but it can be set to run an arbitrary command to do it, so you can check mail stored on another system. By default it is set to do a colour, shaped, but non-animated, icon: this is apparently possible with xbiff if you tweak the resources. By tweaking the resources of xmailbox you can get animated icons. From Debian 3.0r0 APT
