_Acrylics Engraving and Cutting //Engraved acrylic with led would make your designs glow. //We need to half cut some places to hide the led strip and wires. //Also these 4 pieces of acrylic boards should be interactive to each other, thus i also have to cut a small gap for the wires which can connect led strips on different boards.

_TV
// About 1950s or so, television was the primary medium for influencing pu
ublic opinion.
It’s easy to think it a traditional medium which can deliver news and informations when people see the tv. Nevertheless a real tv is so common that ppl’s already been sick of it, in a way.
