Stasis offers some great animations with a hatch (which can open/close) in the center that shows you either six user-customizable icons or 5 quick access icons depending on which knob you selected. Besides for the hatch door animations this theme also has rotating vents and chambers.
Stasis is available for $6.99 and is compatible with the BlackBerry 8350, 8500, 8900, 9000, 9500 (OS 4.7 or 5.0), 9600 and 9700 series. I’ve included a video which demonstrates this theme’s animations after the jump. Check it out and let me know what you think in the comments!
