Make images out of triangles

To get the GUI version working in a virtual environment named tri_image on Linux (Linux Mint), I had to install the
ubuntu package python-pil.imagetk then copy
/usr/lib/python2.7/dist-packages/PIL/_imagingtk.so to ~/.virtualenvs/tri_image/lib/python2.7/site-packages/PIL/_imagingtk.so.
Example usage:
# For GUI version (you can actively watch the evolution)
python gui.py ../examples/input_images/mona_lisa.jpg ../mona_lisa_500 --num-triangles 500
# For non-GUI version
python application.py ../examples/input_images/mona_lisa.jpg ../mona_lisa_500 --num-triangles 500
To make a video of the results:
# 10 frames per second, taken from the images in the folder picasso_500
ffmpeg -r 10 -i picasso_500/intermediate_%03d.png picasso.mp4
To make a complicated video with variable speed and side-by-side comparisons:
run make_video.py (which is just a hacked together script, not at all polished), then copy the 1st hundred images
into a folder named 1, then images 100-499 into a folder named 2,
and the rest into a folder named 3.
Then, run:
ffmpeg -r 10 -i 1/combined_%04d.png picasso_1.mp4
ffmpeg -r 20 -start_number 100 -i 2/combined_%04d.png picasso_2.mp
ffmpeg -r 30 -start_number 500 -i 3/combined_%04d.png picasso_3.mp4
mencoder picasso_1.mp4 picasso_2.mp4 picasso_3.mp4 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1800 -o picasso.avi
Here's an example of it in action. The vide has a non-seeded version (ran with --randomized flag) on the
left, and seeded version on right. The time is in hh:mm.
