References/Examples: For this technical looking-outwards I inspected: createWriter(), video pixels, continuous lines, sound effect, loadJSON(), saveStrings(), and letter.
Most of the references and examples I encountered were all interesting and useful (since I am still learning what is possible in p5js, let alone what kind of interaction is possible with and within the computer). So, I found the loadJSON() function more useful than interesting--in the sense that I now know that I can load data (for my interests, textual data) into p5js using this function (I learnt how to receive data from a JSON file previously in my coding for digital humanities class). The example on how to how to write text (saveStrings() to a file is also useful in tandem with the loadJason function.
Libraries: Looked at: p5.speech, Vida (p5js + motion detection), p5.geolocation, ml5.js (got a peek last week working with Golan on a custom classifier), p5js +ASCII art, and p5.riso.
All of the libraries I looked at were interesting! But I thought that the p5.riso library was especially intriguing since it is a library designed to eventually generate a physical object (a risograph print)--I have seen this used a few times to convert shader-generated graphics into a static poster.
Glitch.com: I looked at friendly-words and hello-magenta on Glitch.com. I think friendly-words would be a useful if I need a good bank of words to draw from. Hello-magenta is interesting because it helps you make music online (might be cool to use for collaborative music composition).
