Beat Blocks iBook?

Does anyone out there use an iPad? Would you like all the lessons and examples, leading questions, etc, in a digital format? I keep feeling more and more that this needs to happen. My question is, what would you like included? Of course lessons and diagrams would be there, but what about real live assessment examples? Videos of real live humans interacting with blocks? If you have ideas to help me shape these ideas, please email me at beatblocks@icloud.com.
