# The effects

hyperbin ships three effects, all driven by the same rule: **the effect
grows with what's in the Trash** and settles back when the bin is emptied.
None of them is a fixed loop — each reacts to your bin and your pointer.

You can switch effects at any time from the menu-bar item, under
**Effect**. [Settings](/docs/hyperbin/settings) covers the amount and
threshold controls that apply to all three.

## Flies

A swarm of flies over the bin.

- They **land on the bin and walk about**, take off, and pass behind it —
  flies that overlap the Trash's own artwork are masked away, so they read
  as passing *behind* the icon
- The motion comes from steering behaviours (wander, separation,
  containment) rather than a keyframed path, so it never loops visibly
- Bring the pointer near the bin and they **scatter**
- The swarm's size follows the amount setting and the bin's fullness; with
  an empty bin the last fly leaves under its own power

## Ooze

A translucent green gel that **fills the bin and runs down the outside**.

- The look is transmission: you see the bin *through* the gel, refracted,
  with real highlights
- As the bin fills, the gel climbs and the film running down the outside
  thickens; a **puddle gathers at the foot**
- The gel has **eyes** that open, blink, and glance around — seated on the
  surface so the body swells and closes around each one
- The eyes **follow your pointer**: bring the cursor over the bin and they
  converge on it until it leaves

> **Note — The level is not a gauge**
> The ooze deliberately reads high early on: a half-full bin and a full one
> look nearly the same. That's the intended character, not a misreading of
> your Trash.

## Tentacles

Arms that **reach out of the bin**.

- Each arm feels along the rim, slaps it, coils, wraps around it, and curls
  up
- Arms pass **behind the lid and behind the rubbish** (masked against the
  bin's measured opening) rather than floating over the icon
- When you empty the bin they thrash their way back under the rubbish
- More arms join as the bin fills, according to the amount setting

## How fullness drives an effect

Which effect you get, and how much of it, is set by two things you control
in the menu — see [Settings](/docs/hyperbin/settings) for the full list:

| Setting | What it does |
|---------|--------------|
| **Amount** | How much of the effect — *Just a Little* to *Make It Stop* |
| **Trash Threshold** | How full the bin must be before the effect takes hold (1 MB to 5 GB+), used in *More Trash, More Effect* mode |

When the Trash empties below the threshold, every effect winds down and
stops on its own — nothing keeps running, so an idle hyperbin costs
essentially nothing in energy.
