    // Part of the Exhibition //
    Black Mirror – A New Installation and Moving Paintings
    1st US Solo Show of Robert Seidel Young Projects, Space B210, Los Angeles
    March 22nd to August 20th 2011

    // Press Comments //
    Robert Seidel’s first solo show in the U.S., at Young Projects, is an immersive experience, a sensuous dip into light, color, movement, sound and change […] Seidel’s stream of visual consciousness is well worth dipping into.
    Leah Ollman, Los Angeles Times, April 29th 2011

    Experiencing Seidel's art seems both external to the self and internalized. Mirages come and go as fleeting as thought, with just their collective impact lingering.
    Anne Martens, Flash Art, International Edition, No. 279, July–September 2011

    // Excerpt from the Essay / Behind the Curtain of Things //
    Woven by laser into scarcely discernible forms, gossamer papers inspired by bark beetle traces float in the exhibition space. Light-structures invade these delicate paper beings, shower them with dazzling colour, caress them with flowing powdery haze. A mirror reflects the viewer’s incidence angle of vision and seems to open up a unifying space that nonetheless remains only a surface.
    Ulrike Pennewitz, Art Historian

  2. This is a Quartz Composer GLSL shader patch that ray traces a Quaternion Julia set. The shader is ported from Keenan Crane's Cg version described here: devmaster.net/forums/showthread.php?t=4448

    I've added a crude Ambient Occlusion addition to the shading as part of the ray tracing process is to calculate the distance to the nearest part of the fractal isosurface and so we can get an AO effect almost for free.

    Without 4x super sampling I get up to 30fps @600x400 on my iMac with a NVIDIA 8800GS gfx card.
