Some fellas have gotten together to form Baltimore Node, a self-described hackerspace where computer/techy-minded people can get together to work on interesting little projects.

(A hacker, by the way, is not necessarily a bad, evil person. Hackers can be good, as I'm sure the folks involved with Baltimore Node are.)

Hackerspaces have been popping up all over the world. Members use the Web to connect with each other and other spaces -- just check out the Hackerspaces.org site for the big picture.

Baltimore Node's first group project will take place tonight, from 7-10 p.m. (Event details.)

They'll be building lamps whose color can be changed by simply Tweeting a hexadecimal color value to it.

Now, hackers, why would you want to do that? Short answer (I think): Because you can.

But, more importantly, it's an excuse to dip your toes into Arduino, a nifty open-source hardware/software programming platform that enables people to create interactive gadgets.
