Have you ever wanted to just sit around and imagine you live the universe of Star Trek? Well an inspired Trekkie has made it easier by uploading 24 hours of the sound of the USS Enterprise-D engine noise (at idle), or if you prefer there is also 2 hours of the original series USS Enterprise.
Relax on the Enterprise
The following YouTube video, which appears to be going viral, comes from crysknife007 who says he loved the ambient sound of Star Trek: The Next Generation so much he cleaned up a clip from the show and looped it for 24 hours. (also available as a download)
And if you want to go old school. Here is 2 hours of engine noise from the original USS Enterprise from the 1960s Star Trek. [NOTE: Video has no image]
