DestroyTwitter is a compact though robust Twitter application built to run on Mac, Windows, and Linux using Adobe AIR. It consists of a series of canvases that constantly update to keep tweets up-to-date using notifications that appear when a new tweet arrives. DestroyTwitter uses a minimal amount of memory compared to its AIR-based alternatives without sacrificing functionality and performance. As a result, it can easily run in the background as an automated process.
