PY_02 Processing Galaxy

First pass, drawing blinking pixels on a canvas with gradient

It'd be cool if the size and brightness of stars vary by their distance from the center

Use A and D to control the rotation

Stars leave tracks as if it's time-lapsed

Click to add/remove stars

...something's off? Whenever I click after applying rotation, the stars spawn at the wrong location

Fixing it by adding relative rotation offset to the mouse location

I also noticed that the gradient is cut into several pieces, which I suppose is caused by multiple overlays of images with alpha...
Adding a random offset to the alpha solves the issue

I also added this dragging function to scatter the stars around when dragging

Add a random color to the star class

Meteorites! Generate from the edge of the screen

And blackholes! Here's a start animation for it

...with 4 spiral arms, which hint its radius t attract stars!

and I wish something would happen once they meet each other!
