Examples of how Social Media can Be Integrated With Interactive Design Projects?

I was thinking along the lines of The Happiness Machine. You write a positive SMS and the machine prints out a little slip of paper with the message on.

There was also another project where light bulbs were linked to hashtags and every time someone tweeted using the hashtag, the lightbulb went off.

Sorry for the vague examples and question but any projects remotely similar would help a lot.

Thanks :)

Great design resource
