Seizuredome!

This is the framework for a geodesic dome. It will be wrapped in mylar blankets to make the interior reflective and lit with a very powerful red LED strobe. Anyone inside it will be able to get brain-machine-like effects by sitting and looking at the strobe.

Of course, it could also cause seizures in previously undiagnosed photosensitive epileptics, so there will have to be warning signs.
