If you have no USB-A ports and no HDMI output (a recent MacBook for instance) this would all run you 15 + 4 + 10 + 4 = $33. If you have both of those things it would just be 10 + 4 = $14, or $10 for just the capture dongle if you bring an HDMI cable.

			We will talk about how you can use external media in the feedback loop. You can use your own clips or videos but here are a couple small GIFs that I'll use to demonstrate the concept. You can download these to follow along and play with.

	~~[optional: put~~ your ~~longer description here]~~		Video feedback is an awesome, hands-on way to create wild, real-time visuals that let you explore fractals, chaos, and procedural art. The classic hack is to connect a camera to a TV, then point the camera at that same TV for instant psychedelic fractals. But you don't need that stuff to do this, the same effect can be achieved entirely in software on your daily-driver personal computer. This workshop will guide attendees through a simple but very powerful setup for experimenting with video feedback through mild misuse of OBS (Open Broadcaster Software). OBS is one of the most popular programs for streaming, allowing you to easily record or stream your visuals and incorporate videos or other software into them. It also has a ton of capabilities for processing the feedback, ranging from contrast and hue adjustments all the way to coding custom shaders. We will look at some of the many manipulations possible within OBS and talk about how to explore video feedback further with other software and hardware.

If you can [https://obsproject.com/download install OBS Studio] beforehand, great. If not we will make sure everyone gets it installed at the start of the workshop. I hardly need to do any setup so feel free to show up early.

	~~[put~~ your ~~short description here]~~		Explore the infinite creative possibilities of video feedback using just your laptop and OBS (free video software). This workshop will scratch the surface of the groovy fractal universe of real-time video feedback. Laptop required. Caution: While participants will try to tame the vortex, playing with feedback can produce rapidly flashing lights.
