I was just playing around with the new fireworks, and came up with this.
This is a randomizedfireworks display that will shoot anywhere from 25 to 125 fireworks, and then ending of with a big finale. Everything is automated with redstone and command blocks, so you just have to click a button and enjoy the show.
I have optimized all the components used, so the system is infinitely expandable. The system takes advantage of some redstone bugs, and might not work in the planned 1.5 Redstone Update. To experience the show as intended, it is recommended that you use Minecraft version 1.4.6.
The show is not a one time use, and can be used from 1 to 1143 times. All information about that below.
The show is reusable, but does have limitations.
In every show, there will be fired anywhere from 49 to 149 rockets.
The number of regular rockets will vary from 25 to 125 but the finale will always consist of 24 rockets.
The best show will be achieved between show number 1 and show number 45 but the can be used up until show number 228.
The show can still be used after being used 228 times, but this will only be the finale, and not the regular rockets.

And here is the first part of the finale, but you will have to download it for yourself to see the rest.
