Unique SCS Opportunities Offered?

What undergraduate SCS research opportunities does Carnegie Mellon offer? What special programs for students to pursue their passions outside the classroom? Internships opportunities?

I have extensively looked through CMU’s website and found numerous programs they offer, but could someone name some of the most popular undergraduate SCS programs? From CMU’s info sessions, I know they have a great study abroad program; are there any other interesting programs they offer?
