Pattern Blocks -- Power Polygon Edition

A version of the PatBlock program using a set of blocks derived from "Power Polygons". Some of the power polygons need to br produced by scaling up the starting blocks by a factor of 2 (use the right-click menu (control-click on Macs)).

NOTE: Java-capable browser required. The Java applet will require you to grant it access privileges. Only do this if you are prepared to trust this site, software, and the author!

The user interface for Patblocks is a little idiosyncratic, so here's a suggestion for getting started:

You can always drag out new blocks from the blocks on the left edge of the screen. You probably want to avoid the pentagon and octagon, at least to start.

The Window button moves the pattern block program out of the web page and into its own window, so that it can be enlarged for bigger and better patterns.

The Save button lets you save your pattern in the pattern library.
