A kaleidoscope, with its shifting, symmetrical patterns, can induce a meditative state by influencing brainwave activity. Specifically, it can help decrease beta wave activity (associated with active thinking and alertness) and increase alpha and theta wave activity (associated with relaxation and deeper states of consciousness). This shift can be facilitated by the kaleidoscope's ability to bypass the analytical part of the brain (neocortex) and engage the right hemisphere, potentially boosting creativity and receptivity to new ideas.
