I recently stumbled upon a rather interesting concept defined by Wolfgang Köhler in 1929. The bouba / kiki effect is based on an experiment whereby viewers are shown two shapes; one shape is curvy and cloud like and the other is jagged and angular. The view is then asked which of the two shapes should be called bouba and which should be called kiki. The results were very conclusive in that 95% to 98% of the people asked said the curvier shape should be called bouba. This result points towards the notion of a synesthesic type remapping of the senses where audio characteristics have an underlying link to visual characteristic.
Its not important I just thought it was interesting
