Collection of project idea

I'm going to collect some larger optional parts for each HW that could develop into a project

PIL - related: make a image tapestry (creates a HUGE image with sub-images are pixels)

• get a greyscale image A  (could be color but would be trickier to match ...)
• get a bunch of random images (maybe from some sort of news feed?),crop/resize each to 100x100
• use PIL to convert each image to greyscale (or not) and get the average (representative) pixel value
• make sure you have an "average" image for each pixel color in image A
• stitch together a large image where each original pixel of image A is substituted by a 100x100 image with the same color (greyscale)
