Please excuse the n00b question.
Is there sample code or a library for a mouse interaction similar to Kawandeep Virdee’s Confetti Vortex?

I have looked through the topics and do not find anything similar.
Thank you!
Next questions:
- Mac input
- Porting to Git and Github from Openprocessing
- Input from an external sources

Hello and welcome to the forum! Great to have you here.
reminded me off this [Pulses / Examples / Processing.org](https://processing.org/examples/pulses.html)
You can make a growing shape instead of the flower.
here is the shape:
```auto
size(600, 600);
float x=width/2; // =mouseX;
float y=height/2; // =mouseY;
beginShape();
vertex(x, y-80); // TOP
vertex(x+40, y); // Right middle
vertex(x, y+80); // Bottom
vertex(x-40, y); // LEFT
endShape(CLOSE);
```

@Chrisir Thank you!
Very cool, now I know what it is called “Pulses.”
Happy New Year.
