An image comparison tool based on the IPython interactive widget architecture.
The notebook included here is an illustration of how to build an IPython widget for a real-world use case: intercactive exploration of the differences between two images (inspired by Github's image diff).
Note: Since this notebook contains interactive widgets, if you read it on IPython's nbviewer you will not be able to see the interactive effects. You'll need to download it and run it locally.
Thanks to Neil Lawrence, from U. Sheffield, for the invitation to speak at his data science meetup. A lunch discussion provided the motivation to write the first version of this tool 15 minutes before the seminar, and it worked with plenty of seconds to spare.
