How the Bubbles screensaver works

On startup the saver spawns a set of bubbles — 24 by default, adjustable from 8 to 60 — each given a random depth value between 0.35 and 1. That depth scales both the radius and the rise speed, so nearer bubbles are larger and climb faster while distant ones stay small and slow.

Every bubble is drawn as a radial gradient: nearly transparent in the center, brightening to a denser rim near the edge, which gives the hollow glass look. A small bright white dot is painted in the upper-left of each sphere as a specular highlight, selling the reflective surface.

Each frame the bubbles drift upward by their per-bubble velocity scaled by your Rise speed setting, while a sine wobble nudges them slightly side to side. When a bubble passes off the top of the screen it wraps back to the bottom at a fresh horizontal position.

The bubbles are sorted by depth so smaller, more distant spheres render behind larger ones, producing a simple parallax sense of foreground and background against your chosen background color.

A worked example

With the defaults — 24 bubbles, max size 70px, rise speed 4, tint #7fd4ff over background #0a0e1a — you get a couple dozen pale-blue glass spheres of mixed sizes drifting calmly upward on a near-black field. Raise Bubbles toward 60 and Max size to 180px for a denser, chunkier tank, or push Rise speed to 10 for a brisk, energetic climb.

Yes. The Bubbles slider sets the count from 8 to 60, and the Max size slider controls how large they can get, up to 180 pixels.
