Thing 21-Free for All: I was looking at my ipad to see what apps I might have that weren't added from this whole endeavor. I already mentioned VidRhythm in the video exercise (Thing 14)..this is really cool..so try it..unless you don't like being silly:

https://itunes.apple.com/us/app/vidrhythm/id457548851?mt=8

If you go to: http://sites.mnhs.org/civil-war/ and look in the lower right hand corner there is an icon for MN and the Civil War which is a free app that was publicized when mnhs had the Civil War exhibit. It is an interactive text book with some audio and you can look at exhibit items and hear/read stories and look at some charts and graphs. It's interesting enough that my son has actually browsed on occasion without my asking him too.

MNHS also links to a website with other educational apps from other museums: http://appsineducation.blogspot.com/2011/10/12-museums-apps-from-around-world.html

I also have an app I haven't played with much yet that I got for free from the Minneapolis Institute of Arts called History Hero: https://itunes.apple.com/us/app/history-hero/id661731419?mt=8
