Baltimore Dorkbot

So this site needs a look. I was trying to think of an image that might befit Baltimore and electronics/electricity. One idea I had was to find an interesting image of Thaddeus Cahill’s Teleharmonium. Cahill was an early pioneer in electronic music and his telharmonium was an electronic organ of sort that broadcast via telephone lines. One of the first successful demonstrations was right here in Baltimore at the the Maryland club. There aren’t many images of the teleharmonium however. Mostly diagrams of some its workings. I included a few. Any other ideas?
