Led table with heat sensitivity, LED ARRAY

I want take my 4X8 desk, Drill a hole every 1 inch and put an LED in the hole along with a heat sensor. Then cover up the desk with a clear bar-top material. Making the desk entirely smooth on top.

When I lean on desk the LEDs would light up where my arms are (heat), or a coffee cup (heat)

I have an attractive secretary coming over and cant wait to finish this program.

Is this project possible? Also, LEDs would do other cool stuff like blink, scroll txt etc. But my main goal it to have heat sensitive LEDS.

Thank you, Steve

Heat sensitive LEDs?! What kind of LEDs are you using? Maybe you should use a few thermistors for temperature sensing?

I don’t think arduino will be able to handle so many sensors. But I may be wrong.
