Neurological recovery board design

[mohamed.fazez]

Hello,
I work in a physical therapy clinic and we would like to design a board with about 32 LEDs spread in 2 circles with push buttons next to them. The patient needs to press the button having the LED on, which turns the current lit led off then another one comes on, then turns it off by pressing a button and so on.
Could anyone please point me in the right direction.
Ps. We don't need to get fancy with touch sensitive button, a simple push button will be OK, and all buttons can be connected in parralel so if any button is pressed, a led comes off and and another one comes on. It will be our job to direct patients to press on the correct button (the one next to the LED that's on)
Thanks.

The Thread is 2yo but I just created such a circuit. (Without seen the video, if it still exist, since I have no FB account)
Maybe it helps to inspire somebody by this circuit.

Feedback is appreciated.
