This contactless temperature sensor has a POV display for the temperature readout.
Here is the github: https://github.com/merlinmarrs/POV-fever-meter
Here is what it looks like in a dark room with long exposure:
The plan was to have the device spell out the message in reverse after displaying it normally to allow a certain frequency of waving the wand back and forth to display perfectly. Alas…this does not work well currently.
I am still waiting for the IR temperature sensor to arrive in the mail.
