hello, can someone tell me where I can download free screen wallpapers to use in the “grid” ? .
I'm asking why I'm going to rent the Indie version of Houdini and I want to know because I think using the free google wallpapers are probably under copyright.

If can help me, I thank you.

here are some of the free photo sharing sites I used
posting to you to find these if they are useful and worthy.
