Switch Button Board

Before this I wanted to make a foot switch for the installation. But I have a few problems to make it work, and because of that, I decided to go for the hand button. I must say that the interactivity will be less the fun (or less aesthetic value?), but I have no time to figure :(

I use an acrylic that I bought from an art shop in Taman Melawati.

...and the result...well, not so neat. haih... clumsy.
