A museum of optical illusions on Kongresni trg in central Ljubljana, with dozens of hands-on exhibits: the Ames room, a vortex tunnel, an infinity mirror, holograms and brain teasers. Touching and photographing everything is encouraged, and the staff help you find the best angles. The format works for adults and children alike, and a visit typically takes about an hour. Open every day.
