- glitch images
- drag an image into the browser window to modify it. this script corrupts some bytes in a jpg image. because of the way jpg encoding works, the corripted file still shows something. inspired by soulwire s experiment in flash. this experiment was created by georg . you can follow him on twitter or explore the source code on github .
+
+ With this app, you can glitch your own images by dragging an image into the browser window. Use the sliders in the control panel to alter the glitched parameters. The image updates in real time.
+ This app corrupts some bytes in an image. Because of the way JPEG encoding works, the corrupted file still shows a corrupted image. It was inspired by soulwire ’s experiment in Flash.
+ This tool was created by Georg . He is always happy to learn about the things that people are creating with his tools. You can follow him on Twitter or explore the source code of this app on GitHub .
+ If you like the glitcher, you can check out some of Georg’s other JavaScript experiments .
+
+ Please note : javascript and modern browsers are required for this app to work.
