Come on in. The porch light is on.

Welcome. I’m Christopher Gabriel Brown — I go by Cri-One — and this is my house. Everything in it I made myself, a piece at a time, over a lot of years. Nobody here will rush you. Look at whatever you like, for as long as you like.

Here is what’s in each room:

• The reading chair — essays and a poem or two, free to read.
• The music room — my original music, streaming free.
• The hallway — a gallery of my artwork.
• The chalkboard — ten mathematical animations, free to watch.
• The workshop — ninety-two invention blueprints and four calculators that run real physics. Sign in, just below, and that door opens too.
• Your shelf — a free sign-in keeps everything you read or buy in your own library.

The reading rooms are open to everyone right here. The calculators and your library open with a free sign-in.

If you’d like to know who built the place, my story is here. And if you have a question, the address at the bottom of the page comes straight to me. I’d be glad to hear from you.

Make yourself at home. — Christopher
