Ha, I'm currently wearing my 251 course staff ("yer sould = pwned") shirt as I type this. The most recent website is contained in https://colormygraph.ugrad.cs.cmu.edu/ https://colormygraph.ugrad.cs.cmu.edu/ . One of the TAs used the course as a testing grounds for his pedagogy research, which has students grading each other (doing "verifications") as part of their assignment, and spent a while building the course infrastructure to support it. (We then grade them on their grading.) After a bit of tweaking (e.g.: we quickly realized the students would primarily benefit from verifying a couple problems rather than all of them), it wound up working really well!
