veins - a weird visual toy



I call this particular bit of code "veins" because it ... sorta looks like veins.
Put less creepily, it's a bit like an old Windows screensaver (the one with all the random tubes) crossed with a Jackson Pollock painting. But less elegant.

It's a pretty simple toy - I just get the pixel color of wherever the user is clicking, then I send our four "pix" objects that carry that color in random directions, creating random lines at 90-degree angles to each other. It's kind of neat on its own, but clicking many times in a single location / holding the mouse button down also creates an interesting corruption-style effect, or a wavelike effect if the mouse is dragged.

For performance considerations, I stop the "pix" objects after 500 steps, so I can rapidly click/hold the mouse button down without bogging down the browser.

Stupid Triangle Thing

...is the best name I can come up for this strange interactive computer contraption I've hacked together. Full demo: To start: I made a p5js sketch which would do several things. 1. make triangles onscreen on a certain input 2. set colors to each triangle 3. randomize the position of each point of each triangle, the color of each triangle, and the background color on a certain input 4. interpolate the movement of the triangles and the color changes from one random point to another 5. allow the user to control the rate of interpolation (speed) This was, as it would turn out, the easy part. I got it running in no time. Then, I got an Arduino interface working which would return values from 1-10 for a pot, as well as separate values which I decided to label "11" and "12" for two separate buttons. Code here: https://pastebin.com/qciFiYec I got it returning the values needed to a serial port in no time, as well. Circuitry: I then

Squeezy Circle

My latest invention takes after the subgenre of infinite runners akin to the Flash classic Helicopter and the infamous iPhone game Flappy Bird - namely, ones that require the player to finesse a specific input to weave between randomly placed pillars flying at the player on a 2-D plane. In my case, it's an FSR controlling a sphere. It's particularly jerky, since it's not interpolating the inputs, just assigning them directly to the sphere, but it works well enough. I have a series of blocks objects that steadily approach the sphere, and delete themselves once they're offscreen. They check for collision with the ball only when they're at relatively the same x position, and compare the ball's center coordinate with their own openings. Checking the center of an object as opposed to the entire thing is a practice employed by many 2D 'shmup games, which I am terrible at. Since I seem to be incapable of writing solid serial communication on my own, I borro
