Picturius Bottian Twitterbot

Twitterbot: @Picturus Bottian

What the Bot does: The Bot repost an filtered Image to you (if you send him one). Therefore he choose random 2-4 individual filter functions and create a new Image. He also give back a short sentence which he choose randomly. If you did not send and image and just text... he answer with: "No image".

Ideas andP roblems: I want to do an image bot which is not 100% clear what he creates. So I play whith this random and filter functions. To get on every processed image an individual look i had to go more and more abstract whith his output. So I increase the numbers of filter functions, put in more distorted filters and increase the minimal number of filter routines on every image.

Thanks to: Thanks to Stackoverflow, thanks to the smaller Blogs and Forums I arrieved via Google, thanks to effbot, thanks to Pillow and last but not least thanks to Martin and Sebastian.
