The problem
The bilateral lightbar was designed for a room. You hold it up to your webcam. The image compresses. The client loses the sweep. You switch to tapping and wonder whether something is lost in translation.

BLS Studio was built to close that gap — a purpose-built bilateral light that runs entirely in the browser, requires nothing from the client, and delivers a full-width sweep through the screen share you are already using.

How it works
01
Open the file in your browser
No installation. No account. The HTML file opens in Chrome, Firefox, Safari, or Edge and is ready immediately.
02
Configure for this set
Set speed, shape, color, size, diagonal angle, bilateral audio, and session timer before the session begins. Everything is adjustable without interrupting the client.
03
Switch to Client View
One click hides the control panel entirely. Your client sees only the light moving across a dark screen. Controls fade after a few seconds. Move your cursor to the bottom edge to bring them back.
04
Share your screen and begin
Share the browser window through Zoom, SimplePractice, Doxy, or any platform you are already using. The light travels edge to edge of your client's monitor.
What it does
Full-width sweep
The light travels edge to edge of the client's monitor. At normal laptop viewing distance, that is a real bilateral sweep — not an approximation.
Client View
Hides all controls on demand. Your client sees only the light. The overlay fades automatically and returns when you move the cursor — invisible on the client's end.
Bilateral audio
Three tones — soft sine, click, bell — panned hard left and right on each bounce. Useful alongside visual tracking or independently with headphones.
Speed & angle
Adjustable speed, diagonal angle (−40° to +40°), trail fade, and glow. A slight downward diagonal mirrors the angle of a hand-held lightbar.
Dot or bar shape
Toggle between a circular dot and a horizontal bar. The bar shape is closer to what clients recognize from in-person sessions.
Session timer
Runs simultaneously in both views. Presets from 5 to 30 minutes. You and your client track the same clock without either of you needing to watch a phone.
