3D graphics in Resolver One using OpenGL and Tao, part III: Stock prices

I've done another 3D example in Resolver One. This one uses Yahoo! Finance to download the close prices over the last two years for every stock that's currently in the Dow Jones index, then charts them in a 3D window which you can pan and zoom using the mouse. Here's a video showing it in action (click the image to view):

Here's how you can try it out:

• If you didn't already, download and install the Tao Framework, a set of multimedia libraries that (among many other things) makes it easy for .NET programs like Resolver One to call the OpenGL 3D graphics libraries. (UPDATE: Rick comments below that when he first installed Tao as a non-admin user, it didn't work, but when it had been reinstalled by an administrator it did work. It sounds like Tao is failing silently when installed by a non-administrator, so look out for that.)
• Again, if you don't have it already, download Resolver One. (It's free to try.)
• Get the sample spreadsheet, along with its supporting Python code. Unzip this file somewhere, and then open the file 3dShares.rsl with Resolver One. (An alternative: if you're on GitHub, you can clone a repository there that contains all of my Resolver One 3D samples so far.)

I won't explain in depth how the spreadsheet works; there's not actually all that much there beyond what I described in my last two posts about 3D graphics in Resolver One.

I'll be tweaking the performance of the sheet over the next few days, and I'm keen to hook it up to the BetFair API so that we can chart gambling odds too, but before I charge ahead with that, let me leave you with a question -- what could I add to make something like this truly useful to someone watching the financial markets? Would it be useful to be able to "fly around" the chart instead of just spinning it around? Perhaps clicking on things could give you information? Or anything else?

What do you think?
