Thanks for this challenge Major Major. BG Texture from Pepsized.com. Image from pngtree I did a sketch effect first and blended that with the original image with the Linear Burn blend mode. Created a stamped layer and gave it a Posterize effect.

Having seen some of the excellent interpretations above I thought I'd be lazy and see if the Droste Effect was still available on-line and sure enough it is at www.photospiralysis.com/ . The first one was done with Firefox using HTML5 and finished off in PS. Then I decided to try the IOS app on an iPad and it works fine so that's the second version - again finished off in PS, Now I have it on the iPad it's going to be very tempting to play some more
