Switch between Frosted Glass and Lava Lamp

Frosted Glass

A static, clean blur. Looks like a piece of frosted glass laid over your screen. Best when you want the overlay to disappear into the background— viewers notice the content you're showing, not the overlay itself.

• Best for: screen recordings, tutorials, presentations, screenshots, professional demos.
• CPU usage: negligible. Uses macOS's native blur.
• Default style for new BlurBoxes.

Lava Lamp

An animated, decorative blur with slow-drifting color blobs. Looks like a lava lamp under frosted glass. Best when you want the overlay to be part of the visual story — useful for livestreams and showcases where the audience can see something interesting on screen.

• Best for: Twitch / YouTube streams, social media demos, showcase reels.
• CPU usage: a few percent per overlay on Apple Silicon. Use sparingly if you have many overlays.
