It's always fun to see companies reference other companies with which they work. VirtualBox is a software package that allows you run several different operating systems in their own virtual machines (like VMWare, Xen, etc). Their about box is great. They have the Suse Iguana (wearing a Red Hat), the Linux Penguin playing a tambourine emblazoned with the Ubuntu logo, the Microsoft "Butterfly," stars (alluding to Mandrake/Mandriva) rising from the fire, and the BSD Daemon eating a multi-colored Apple. No, VirtualBox can't boot OS X, but the apple is probably an allusion to Darwin, which I assume VirtualBox could boot, and upon which OS X is built. Did I miss any logos?
