FOSS gamedev and creative worlds

There are situations when we really need sounds, pictures, models, scripts... to make it meaningful
to continue on a project, but can be difficult to make or get.

Here's a "hydraulic something-or-other" sound I made from the "elevator platform", "rusty door 2", and "engine" sounds. I'm not sure how useful it'll be in-game, seeing as it was more or less just me playing around in Audacity.
As far as the license is concerned, CC0 sounds fine to me.
