I got this keycaps from a friend, but not MR Clickclark. I hope he would not mind for what he've done, because it seems almost the same as his.
I make the eyes and change the Cherry MX black to be suitable for the eyes.
connected the led directly to the USB Vcc+ ...with a resistance like 470 OHM
there‘re 2 drop of Pattex glue in the eyes. just like 2 small concave mirror.
