So I have written some apps and some widgets and was thinking that I might take a stab on a home screen replacement. Lots of choices already out there but might be a fun adventure. However, I can't really find anywhere to start!

Is there even such thing as an example on where to start off with one of these? I've searched around on here and on google and came up dry, except for the items to put in the manifest for it to be called as the home screen default.

FYI, I found that in the SDK there is an example app called Home. It looks to be an example of a homescreen manager. Digging in now...
