The Pi is a very new device, and as a result I have not seen many complete projects (including parts lists); though I expect we will see some projects reach this level of maturity in the very near future.
There are a few sources of inspiration and ideas that you can hook into now though.
You can run a YouTube search for Raspberry Pi (If you do this regularly you will want to sort by date uploaded). This will turn up a lot of breadboard experiments, including hooking up an LCD Screen. Be sure to check the comments section for build details.
You can subscribe to the Raspberry Pi sub Redddit. Anything new an interesting will surely show up there.
You can browse the raspberry pi category at hackaday.com.
You can search for raspberry pi on instructables.
you can search/check the make community forums for Raspberry Pi.
You can check out Mag Pi magazine. they have a few build and coding tutorials.
You can also browse the Raspberry Pi forums, especially the projects section, and the Projects, Guides & Tutorials section of the R-Pi Hub at elinux.
You can search github and github gists for raspberry pi.
You can subscribe to tumblr's raspberry pi tag.
browse Adafruit's list of Raspberry Pi tutorials.
You can also set up a Google alert to email you once a day with a list of resources the Googlebot has found while indexing the web.
You can also join the raspberry pi community on Google+.
you can like the Raspberry Pi Facebook page.
Finally you can check out the Raspberry Pi User Guide that was recently announced.
I realize this may not be the answer you were hoping for, but as I said the Pi is new and it will take some time to develop a community and ecosystem around it.
Don't forget that you can always ask specific questions here as well.
