Havok

Background
Havok is a middleware software suite developed by Irish software company Havok. The suite provides a physics engine component and related functions to video games. In 2008, Havok was honored at the 59th Annual Technology & Engineering Emmy Awards for advancing the development of physics engines in electronic entertainment.

(2000?-)
Logo: On a white background, we see a sheet covering something. The sheet is removed, revealing the word "havok" in black, with a circular saw blade replacing the "o", embedded into the ground. The logo becomes 3D and black particles can be seen near the blade.

Variants:
 * A still 2D version of this logo exists.
 * On 50 Cent: Bulletproof, the logo is included alongside the logos for Sofdec and ADX.
 * On Sonic Generations, the logo is shown in yellow on a black background beneath the Dolby Digital logo.

Technique: CGI.

Audio: None.

Availability: Seen on video games that utilize the Havok physics engine (though most games don't use a logo at all). The still version was seen on Ed, Edd n' Eddy: The Mis-Edventures, the black background version was seen on Sonic Generations and the Sofdec/ADX combo logo was seen on 50 Cent: Bulletproof. The animated logo was seen on games published by Data Design Interactive.
