AYGShell.. wait.. I get it.. doh!

I've been tinkering on Windows CE-based devices since.. um.. well, let's see, my first one was a Philips Velo 1 handheld PC, and I've owned at least one of each generation since then.

However, it was only last Friday when I heard someone talking that I worked out that the "AYGShell.h" include file is pronouced like "Egg Shell".

Anyone know what the history behind the naming of AYGShell? Is there more to the naming than just a terrible, terrible pun?
