[Arduino Shield List] published an updated list of ALL Arduino shields. From the Ethernet Shield (this links to the new one with Micro SD support, Mega compatible) to the more exotic ones.

Sick of trying to figure out which pins are used by some obscure Arduino shield? Can’t tell whether two shields will be compatible with each other?

This shield database arose out of a discussion on the Arduino Forums about the need for a comprehensive online reference for shield pin assignments. It lists as many Arduino shields as I can find along with their pin usage, making it easy for you to determine if particular shields are compatible.

Once again, a community effort makes our life easier. Bookmarked. Thanks Jonathan.
