Extrafile
By now we’ve all seen so many jpg and bmp glitches that they’ve almost become just another effect. Unfortunately, due to the limited amount of image file formats there are only a finite number of ways to exploit them.
Extrafile, by Kim Asendorf, is a great response to this. The application allows one to convert standard image formats to ones that he has created (4bc, bascii, blinx, cci, mcf, uspec, xff), each with their own properties that sets them apart from standard image formats.
