EDIT to add: Saturday 4/26, sorry for the short notice.
For anyone interested...
They will be using light as art and bathing the flood canals with their projects. Artists from all over the world will be participating (well, New York and Japan are specifically listed as well as RPI students and other artist groups.)
Darn, this is only two hours from where I used to live in VT. I used to have to make trips there for work. One of the few times I wish I hadn't moved; this would be neat to see!
