I blame tetrads!

Tetrad nets

If you play too much Tetris, then you should check out the new subpage: The Tetrad Corner. It’s a collection of things I’ve made this week about the shapes used in tetris (‘tetrads’).

The original idea was that it would be cool to have a tetradic phone password. That is, your password makes a Tetris shape on the keypad. I was bored enough this week to actually write a little script for it, along with a PHP class for rotating the blocks, rendering them as a HTML table, etc.

It turned out alright, but fearing that I had begun something as time-consuming as tetris itself, I banished it to a single-page sub-site. The source code is there if you want those crufty HTML-tetrads on your site: (I don’t!)

Now what I do want is a few tetris blocks for my desk, so I made up some nets to print out and cut up. Now I can make a small paper Tetris game! (PDF linked to image above). Neat huh?

A tetris game in the palm of my hand!

Update 12/4: I built these shapes today. There were two tabs missing on the nets (fixed!), so I cheated by using sticky tape. Click to enlarge the cheesily-colourised image.
