This one has a 5 hour time constraint that you have to build a self-running visual system built in TouchDesigner. Once it starts, it runs on its own and needs no input. A noise source passes through a chain of edge detection, feedback loops, and displacement, then gets keyed and colorized. The result is a field of deep blue with a glowing magenta central radial, and a bright white area that rotates with the blue aspect. Three LFOs create a circle in the upper layer, so the magenta shape keeps pulsing and drifting and the feedback never settles into a repeat. You can watch it for a minute and not see the same frame twice. The only input is a keyboard shortcut by pressing 1 sends a pulse that resets the system.<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video controls src=\"https:\/\/drive.google.com\/file\/d\/1Vqr9X4rKc-fqoLx--0YvR307AsoYGO5I\/view?usp=sharing\"><\/video><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Process Reflection<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How did you approach the 5-hour time constraint?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I used the five hours to practice skills I wanted to grow instead of repeating what I already knew. We learned LFOs in class, so I layered them over a noise-based feedback system, which gave me a lot of motion from a small number of nodes. I stopped when time was nearly up and I felt the piece could hold attention. I had hoped to expand the LFO circles or arrange them into a cleaner pattern.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What choices did you make about what to include or exclude?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I included feedback loops, edge detection, and displacement because they keep simple noise changing indefinitely, which lets the system run alone. I left out audio, since getting two visual systems to work together took most of my hours. I also kept the system loose and abstract instead of patterned, which made it less predictable. The reset key used with the node keyboard in was my only interactive element.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What surprised you during the process?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">How unpredictable the system is. Feedback responds strongly to small changes, so I could steer it but never fully control it. In class, people watched longer than I expected, even without audio. They seemed to enjoy not knowing what would happen next. The result differs from my original idea, but I&#8217;m happy with it. With more time, I&#8217;d clean up the visuals and add audio.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Which achievements did you unlock?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I earned the 30+ seconds of attention achievement. People in class stayed with the piece for over 30 seconds, which I didn&#8217;t expect, given there was no sound. I think the unpredictability was what kept them watching.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Description The pressure project is a project that has a time constraint.
