Does anyone know any new ones fo software?

I've recently started a web site to archive Software only Easter Eggs, and I've managed to collect quite a few so far. Check it out here:

hiddensecretsofsoftware.hammocksurvivalguide.com

I'm on the lookout for more, because I'm greedy. What can I say.

I'f you know of any that I haven't already got, then please please let me know by either submitting them on the site, using the submit link on the home page. Or post them here.

Thanks in advance for any contributions
