Today we'll perform some real mathematical magic---we'll conjure up some real-life ghosts. The main ingredient to this sorcery are some properties of x squared that they don't teach you in school. Featuring the mysterious whispering dishes, the Mirage hologram maker and some origami x squared.paper magic.

Here is a nice article about the Mirage hologram gadget. A complete ray-trace analysis of the Mirage toy by

Sriya Adhya, John W. Noé. The history part in particular makes for a fascinating read: https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9665/966518/A-complete-ray-trace-analysis-of-the-Mirage-toy/10.1117/12.2207520.full?SSO=1
