Novel idea: "stamp keyboard"

Maybe you have seen various types of keyboards, even dynamic keyboards made with OLED, but you must not have seen a keyboard made with stamps. Let's take a look at this novel idea from abroad.

This keyboard is completely customized with character portraits from various stamps. Try the feeling of tapping Bach with your index finger and Washington with your ring finger...

In addition to the various character portraits as key identifiers, this keyboard also continuously records historical moments on its side. Pretty cool, huh?
