Great video Jeff. You talked really well through that whole piece. Most people seem to pause a lot and throw in way too many umms and ahhs. You did very well.
The only issue I had was the resolution of the video was very low, and I could not read most of the text on the screen, which makes it a little tough to follow.
Also, correct me if my math is wrong, but if you take two gears of different sizes, lets say one gear is twice as big as the second gear in one rotation of the large gear wouldn't the small gear rotate twice? In other words shouldn't the smaller gears be spinning at a faster pace than the gear in the center? Why do they all spin at the same speed?
Thanks for the video though, it was very informative.

John,
The reason the gears spin at the right speeds is because of how I chose to rotate them. I didn't specify a speed in which the gears would spin. What I did specify is that I wanted to see *exactly one* revolution in a second. Because of this, they are both spinning at the appropriate speeds to make them work together. If I had to work with RPMs, or other math like that, then yes, I could have had to take things like radius of the gear into consideration.

Hey, Jeff. Thanks for the JUXtapose series. I've only seen episode 1, but I'm eager to learn Silverlight, WPF, and Blend, so your series will be helpful. Some suggestions/questions: how about a post on Expression Suite (Blend, Web, Design, and Media) and the output artifacts that each targets. The Expression Suite site is pretty vague on what tool I should use for what thing I want to accomplish. If I'm doing just WPF or Silverlight, what do I need--just Blend to build my XAML? I'm guessing a cousin to Expression Suite is Sharepoint Designer. If I want to host XAML in Sharepoint, what tool do I use--Blend, Designer, both? Also, is FrontPage now dead? In Episode 1, you started with pre-created images and then animated them. Did you create those images in Blend or some other tool (and if another tool, what tool)? Thanks!
