Lots! I combined this with my Tron Recognizer theme as an add-on (drag it above the Tron theme in WinterBoard). Screenshots here show the Recognizer version, but it's the Lightcycle by default.

: Bonus add-on theme, sort of like a sneak peak of my latest theme!

Added 3 sets of Tron Categories icons

Added two TRON SBSettings themes

Altered or added dozens of custom files: a custom TRON dialer, messages, Safari, buttons, program backgrounds, and loading screens.

Added a purple battery mod to replace the blue one (see screenshot). My TRON Recognizer Theme still has the blue battery if you liked that one!

Dark and Sexy new look! Completely new background, sliders, battery, and many more small changes!

Added a bunch of user-requested icons. .

Added and fixed a few icons.

More icons!

Added 35 unique Tron icons! Enhanced lockscreen image, new data-disk sliders, and new blue status bar battery. Some of the icons are stock iPhone 3GS, which I don't have (I only have the Touch), so they are untested.

Fixes battery image #10, which was from a completely different battery mod of mine!

Initial public release.
