The "pixelisation" in some areas is because it's a fractal, and not a 3D-object or anything like that. But since it doesn't really look like a fractal image I guess you notice it more.
The whole image is a fractal, before I added a drop shadow and some lightning effects i Photoshop. :) You can see the original image here: http://saruman.khn.hk-r.se/frwa02/Banana.jpg
Jackpot! look at it its a crisp , clean , clear image with good color contrast it caught my attention. Not alot to look at but very nice indeed! And most of all original! I cant stand alot of people on here taking one picture and changing a little something here or there and calling it their own. No originallity = no talent.
