Thanks to all of your hard work, we started off the semester with a wonderful set of examples of fun things that can be done with existing data streams. Here in no particular order are some that caught my eye:
Fashion! (search for a trend). Being fashion illiterate I have no further comment, except there were several of you who chose this focus, so get together and teach me in a group project later this semseter :).
Pittsburgh overview. Also a nice example of using Angular to make it pretty.
