FlashBug!

A colorful moving background which overrides New Tabs opened. Customizability ranges from colors of the metaballs, the size of them, and how many are on screen. The extension is extremely light and leaves Chrome's performance unnaffected; older systems may vary. A minimalistic extension which only affects the New Tab page; there is no search bar in the middle of the screen for New Tabs, however any typing in the New Tab page will automatically be rerouted to the URL bar, in no way hindering the ability to search Google.

To customize your background, click on the top-right puzzle icon, and in the dropdown you will see FlashBug! Clicking FlashBug! will open the customization window.
