Macquarie OSA Student Chapter present their entry to the LaserFest Laser Graffiti Competition.

By preparing our own software, we have produced a laser-driven version of the much-loved arcade classic, Pong. This building-sized version of the game, played at the end of laser beams is intuitive and fun, exhibiting just one of the many uses of lasers. With a red laser controlling the movement of the upper paddle and a green laser controlling the lower, we demonstrate Pong at the speed of light.

We chose to abandon the usual planar approach to laser graffiti and instead used a multiple projector arrangement and the Macquarie University Observatory domes to add a surreal twist to our graffiti. In the dead of evening we created our masterworks across two domes, adding previously unknown dimensions to laser graffiti. By using the Macquarie University lotus logo as our brush, we were able to create bizarre patterns with awesome impact.

Finally, we attacked the ultimate canvas: the human face. Using a low-power, eye-safe laser we altered the appearence of one of our chapter members with startling results. Surreal dripping effects, avatar-isation and super-hero masks transform our subject beyond recognition.
