Introduction ============ .. figure:: _static/tm_blink1_site_logo.jpg :align: center The `blink(1) `_ is a tri-color USB LED visual aid, which has multi-language software support. It can produce any *RGB* color, which can then be enhanced in many different ways including variable pulse frequencies, different brightness levels and arbitrary patterns. The challenge is to code something awesome using the `blink(1) `_, based on creativity, coolness, and usefulness. This project utilizes the `blink(1) `_ to represent visually the current build state of the LCO software system.
