| I also made the gif version of Kaleidoscope by make 35 different images each turning 10 degree of the source image.
| | The next step is to make the bot gives more feeling of Kaleidoscope. The nice part of Kaleidoscope is whhen one rotate it around and see the abtract patterns moving. |

| | Last step . . . for the summaery event , I improved a bit the quality of the |
| n= 10
| | GIF by editing the code to be able to make best quality it can and also the final GIF is not larger that the twitter status update limit. |
| outfilename=[]

| clip.write_gif("%s.gif"%filename)
| |
| image2 = Image.open('tweetimg3.png')
| |
|
| |
|
| return image2,clip
| | So I added lines of code to get the size of the final GIF and resize it if it exceed the limit. |
