I want to play with it, but I can't seem to find a link to any windows compatible version of the software.
The code is hosted on their Github page; where they also have a pretty detailed guide for using the code. There's no compiled Windows executable to use that I'm aware of, yet. DeepDream is written in Python using IPython. Python's a really simple programming language, and IPython gives you the immediate results of your code; it shouldn't take you more than an afternoon to get the GitHub code up and running if you wish to, even if you're new to programming. The official Python tutorial is really accessible, it's how I first learned programming; there are also free courses available at Code Academy. Python can be used for a huge range of tasks, I think it's a tool that everybody can make valuable use of, whether you're into programming or not. Also, here's some eyecandy from DeepDream from their GitHub page. I especially like the beagle-butted knight.
It's down right now, but there's a web interface for it here.
