Nice little animations on faults

This site: http://www.iris.edu/hq/programs/education_and_outreach/animations/2 has simulations on the four basic categories of faults.  I found it useful because the animations are all there in one place and there is a little bit of easy-to-understand text describing each type of fault. As a review of the different types of faults, or as part of a comparison activity this site could be quite useful.  These animations also include one type of fault (an oblique fault, which is really like a combination of a dip-slip and a strike-slip fault) that was not covered in our text as well as a little information about it.
