Tobuscus

Background
Tobuscus was launched on YouTube on May 14, 2006 by Toby Turner. The channel is known for its sketches, animated music videos and literal trailers. They also have two other channels named TobyTurner, which is known for daily unedited vlogs called LazyVlogs, and TobyGames, which is known for its Let's Play videos.

(2010?-)
Logo: On a concrete-like background, the company name in a  blocky font with a texture zooms out from the center of the screen, as the screen slightly shakes. After a few seconds, two metal doors close from opposite sides, causing sparks to emit out. Then, it opens again, transitioning to the start of the video.

Technique: Possibly After Effects-like animation.

Music/Sounds: A whoosh, followed by Toby saying the company name, then some metal sounds from the doors and ending with another whoosh when they open.

Availability: Can be seen on most videos produced by the channel likely since 2010, although they usually tend to omit this intro in most cases.
