I'm a computer technologist / artist / composer in the Los Angeles area. I blog about my various projects at

I've done a lot of mosaic art using the Flickr APIs, and co-authored Flickr Hacks, from O'Reilly, with Paul Bausch.

I'm a little obsessed with circles, radial symmetry and mechanical instruments.

I work amongst an awesome collective of nerd/hipsters at Topspin in Santa Monica.

I did some mosaic posters for squared circle, and a day in the life, here on Flickr:

Squared Circle Mosaic: Giant Peach

One of the first things I did on Flickr was to make a number of fun-to-use Flickr Colr Pickrs. Check 'em out!

I also made the world's first Flickr Chia Pet, an experiment in collaborative defacement.

    "Ah, I was beaten to the punch of writing a testimonial for jbum, who is really one Krazydad! Seriously, jbum is one of the real-deal folks on flickr who make this community so awesome! The sense of community is evident in all the loving work he does to make the "Squared Circle" posters and help with others like GustavoG to make the graphs, hacks and poster projects happen. Look at his websites for a great deal of fun. This guy always has something good going on!"

    "I can't believe i'm the first to write a testimonial to this guy. He's hooking up the squared_circle group with some fantastic poster possibilities and making some of the coolest collaborative projects on Flickr! possible.

    He's got all the right skills to take Flickr! to the next level. He's taking great pics and doing amazing things with them. He's the first to pull these really collaborative ideas into a bigger-picture schemata. He's all over Flickr!

    Thanks for all your really rad work Krazydad."
