The Polyomino Database

This is the test site for a database of polyomino tilings. This first version went live on May 1st 2006. I make changes to it every day. This is a personal project and I follow no particular release discipline... except to note that, for now, It's still in testing.

If you come across this site and are interested, please drop me a line, poly@omino.com. Put "polyomino" in the subject line to get past my spam-no-spam scripts.

Feel free to create a wiki account and add some tilings. Feedback appreciated. Write directly on the main page here if you like! This is a work in progress and feature-suggestions are very very very welcome.

Getting started

The <omino> Extension

An important feature of this site is dynamic polyomino rendering. It's nice to talk about the T pentomino () and refer to it visually without a lot of tedious file-uploading! It's so much nicer to just say instead of something longwinded like "the 3 x 5 rectangle formed from two P pentominoes and the T pentomino, the arrangment of which is left as an exercise for the reader," don't you think?

Here's the syntax for embedded polyomino rendering:

Enclose a tiling pattern like aaa-aa-.aa in <omino>aaa-aa-.aa</omino>, to get: 
.

Free *omino* gif-generation

You can use this polyomino rendering service from anywhere on the internet!

You can dynamically generate a polyomino tiling image with a url like:

    http://poly.omino.com/img?omino=aabbcc-aaccbb

This can be handy for several reasons

  • Generate a one-off that you then copy,
  • Or as a live link from, perhaps, other generated data,
  • Or just to embed as handy image.
