Clavilux is the term coined by the artist Thomas Wilfred to refer to his mechanical invention that allowed the creation and performance of lumia, which was Wilfred's term for light art.
While Wilfred intended the term to refer to any device that could be used to perform Lumia, the name Clavilux was not widely adopted by other artists working with light.
The only other artist known to have built a Clavilux is W. Christian Sidenius, who was an ardent admirer and later good friend of Wilfred's.
Sidenius built a theatre behind his home to house his Clavilux and host Lumia recitals during the summer months.
A 501(c)3 not-for-profit, Clavilux.org, has been formed to restore the Model E to working condition, and it plans on holding public recitals as soon as the machines are functional.
