I know. Had a hard time finding the app myself. It's actually called dxTop: Home Alternative. Do a search in the app store and you should be able to find it there.
knowing that DxTop can take a screen shot what are the chances of a stand-a-lone app to do this being developed? I don't want to use home... i have another home replacement I prefer but would love to be able to take screen shots without using the SDK.
