figured i should make a thread on the construction of this. i found a supplier near me that has the blue acrylic sheet i need 3ftx2ft for $23 i will be building the frame with 2x4s and inside the shadowbox i will have dry rock rubble with spray foam and epoxy/zipties holding it together. im going to paint the rock with spray paint (not sure on color yet... Purple? dark blue?) behind the rock will be hardboard painted blue. this will be lit by a RGB led strip from ikea. im picking up the acrylic on friday so contruction starts then. ill take alot of pics of my process. wish me luck!
