I was all set to “officially” annouce whereslunch.org yesterday, and then I tried it in Internet Explorer and it was a mess. Consider this a preview release, and please use Firefox to give it a shot 🙂 Doors open for questions/comments, especially on how ugly it is. (it is ugly!)
For my math circle talk, I think the second part will be on Huffman coding. The upside is I think I can talk about this for long enough and it lends itself well to a worksheet. The downside is it’s not really that related to graph color. But I think I’m gonna go with it because I’m running out of time.
