This ended up a lot longer than I intended. My sincere apologies.
This is also the first time I've used Camtasia to do one of these kind of things. Hopefully it'll work. Not filled with confidence because Vimeo is doing its "just a warning..." thing.
I hope you get something out of this rambling demo of emfluid. If you have any specific questions either leave a comment or find me on Twitter (@lightinganthony).
