A very tranquil, blue theme.
This is a theme which will keep google chrome as simple as it is meant to be. The bars are simply switching from white to blue. It requires a very small amount of disk space to install this theme; about 60 kilobyte. Therefore, this theme is also loading very quick when you start chrome. The new tab page is featuring two manta rays swimming in the sea / ocean.
Some information about the manta ray (from wikipedia):
The manta ray is the largest species of the rays. The largest known specimen was more than 7.6 metres (25 ft) across, with a weight of about 1,300 kilograms (2,900 lb). It ranges throughout tropical waters of the world, typically around coral reefs. Mantas feed on plankton, fish larvae and the like, filtered from the water passing through their gills as they swim. This feeding strategy allows them to grow larger than other ray species. Mantas have a variety of common names, including Atlantic manta, Pacific manta, devilfish, and just manta.
Totally restarting Google Chrome may be required for an aero theme to run properly.
