Topic: Artistic Use Of Compression Distortion
This isn't really a support issue, but I thought you might find it interesting. (I would have put it in a general discussion section, but there doesn't seem to be one here.)
I took a pic, saved it several times with maximum lossy PNG compression, then added some white noise and saved a couple times as low quality JPG. The results were actually quite nice. The artistic effect looks best on the bear (almost looks like fur), but also gives the whole image more interest.
Here's the artistic pic http://allspark.net/cypherswipe/heromachin...nestylized2.jpg
