Ghost Cursor

How this effect works

Every frame the effect writes down where your cursor is, with a timestamp, into a rolling buffer that only keeps the last few seconds. That buffer is the whole trick. The ghost doesn't follow your cursor — it asks the buffer a question: where was the cursor DELAY seconds ago? It reads back that older position (interpolating between the two nearest samples) and eases toward it, so it retraces your exact path a moment behind you.

The trail is the same buffer drawn as a line, each segment faded by how old it is. And when you stop moving, instead of catching up and freezing, the ghost rewinds to the start of the buffer and replays your last gesture on a loop — the haunting bit. Delay sets how far behind it lags, smoothing how loosely it chases, and fade how long the trail lives. This is a TinkerFX signature: it turns your own movement into a character.
