Depth of Field Web sample: opinions wanted

I'm working on the various possibilities CS5 will have for education of new photographers or for more experienced ones to re-enforce concepts.

So today I spent the time to download Flash Catalyst Beta and produce a depth of field comparison flash application I put on my website. Unfortunately the beta only handles files up to 15mb so the final result is far less complicated than my end goal but I wanted to make sure it works for folks on the web.

Here is the link with the app being at the bottom:

What I would like to know from you is:

1. It takes time to load is it too long?

2. are the controls simple? Would you prefer the images to change at roll over as now they change at click?

3. How is the design as far as look, fonts size, etc.

The final product has to wait for the full version to be released but I'm really tempted with the possibilities it offers.
