We are seeking funds to expand The Illusions Index. In particular, we are seeking funds to pay for (1) the development of further audio, video, and multi-modal illusions, and (2) to develop interactive content that will record your reactions to illusions, the strength of the effect in you, and allow you to see how you compare to other users.

We would be very grateful for any donation that you might care to give.

Staff and students at the Centre for the Study of Perceptual Experience have developed this open-access resource for the benefit of the public and for other researchers to use and draw upon.
