Download and unzip to find 10 displacement maps. You can increase their resolution for better results.
Credit goes out to ~ec-stock for the image used for packaging.[link]
I've found a great tutorial on Computer Arts which takes an in-depth look at creating abstract photo manipulations using displacement maps.[link]
Please +fav it if you use them and comment. I'd love to see what you do with them. Crediting is not necessary.
