I requested some MODIS NDVI data and that worked out well enough after making my account. The confusing part was the projection. While I knew that MODIS had a unique sinusoidal projection I didn't think too much about it. Anyways, when opened in ArcGIS it projects funny and it doesn't really work to just reproject it. However, MODIS is fairly commonly used and there is a large Forum post at http://forums.esri.com/Thread.asp?c=93&f=984&t=282340 that discusses how to do it. Now I just need to see if that will work for me.
In other news, I need to read up on something that compares Landsat 5 data to MODIS data in a meaningful way.
