Waterline by Ascenda

Waterline by Ascenda is a macOS screen saver that visualizes Claude Code, Codex, and Cursor activity as animated water.

Waterline by Ascenda is a macOS screen saver designed for engineers running AI agents. It converts live activity from Claude Code, Codex, and Cursor into a water animation where water levels rise as agents work. Specific events such as tool failures and context compactions create visible ripples across the water surface. The software runs entirely locally on Apple silicon Macs using Metal for rendering, without network access or required accounts. Data feeds into the screen saver over a local Unix socket using dedicated agent collectors.
