I'm designing a large light art project and I've been trying to find kits that could essentially make lattice-like structures. For example how stages and cranes have lattice structures. The idea would be similar to wire frame floats for parades, but with adjustable locking joints and plastic or aluminum pipes.
The final structure would be similar to this, but again fully adjustable and able to make different types of latticed structures.
Does anything like this exist?
