I’ve actually been working on something like this the last couple of days. I grabbed this code that I stumbled on at Reddit: http://pastebin.com/G10uqSyZ, and I was trying to write my own python code with a web interface to do the same thing. Now that the Interval Program allows custom functions to be imported I’ve shifted my focus to make a working addon. I’m fairly new to python and javascript so its slow going at this point, but I’m starting to get things figured out. When I get something that works I will post it here.
