For October 3rd I created an anti DRM slideshow (using Open Office Impress). I have exported it into a few different formats (Attached below). I projected the slideshow onto the sides of buildings in NYC including a movie theater, NYU's Bobst Library and an Apple Store.
Feel free to use it yourself to project around town. I hooked my projector up to a laptop and powered the projector using an inverter plugged into my car's cigarette lighter.
