I found a couple of these retro-lamp projects on the internet. They are tagged "retro" because the soft glow LED bulbs resemble old fasioned tungsten lamps. The lamp I made kind of resembles a vintage radio with vaccuum tubes (if you stretch your imagination). The knob on the left is an off-on-dimmer switch, and the one on the right is a rotary switch that gives some control over which bulbs are lit. The "Click Me" button cycles through the various LED configurations.
