The shadow-caster centers around the visual detachment of shadow (effect) from the shade (cause). First, a shadow effect with a highly regular visual pattern (like the Ben Day effect) is created. This ordered effect is juxtaposed with an array of shadow-casters which from the majority of perspectives seem to be arranged and positioned at random.
The second component of this concept centered on the idea of transition and change - allowing viewers an opportunity to witness in action the logic generating the seemingly random cloud of shadow-casters responsible for the ordered shadow.
In addition to obfuscation and controlled reveal, the last governing principle of this approach is the idea of deployability—meaning this object/artifact has key considerations like fixed object size, single axis of rotation and limited moving elements to ensure it is manufacturable within the scope of available technologies.
