Hello people, I decided to make short, slideshow video from all toxic slime textures, I see this very useful for me and others for choosing goo texture for your map and thought I could share it with you.

This video doesn't include all Underground textures, because some of them looks same.
(I could've posted this to Mapping Tips and Useful Links thread, but this is not actual tip and I see this fitting more better here.)
