There’s a group over on Flickr called Mini Kaleids – Krazydad Style that collects images produced with one of my kaleidoscope toys (found on this very website).
The pool is up to 700 images, so I thought now would be a good time to build a Coverpop mosaic of all that eye candy. Here it is. [...]

On December 18th, 1987, the first version of the Perl programming language was released. You can learn more about it in this article over at Wired.

A lot of the visitors to this website assume my tool of choice is Flash, because that is one of the most visible things here, but in truth, a [...]

Here are some new puzzles I’m working on.
These twelve Slitherlink puzzles use the aperiodic five-fold tiling discovered by Sir Roger Penrose. Not only are the puzzles pretty, but the tiling creates a variety of intersections, which makes the puzzles more interesting.

Thanks to Craig Kaplan for providing the dataset for the tiles!

I’ve been enjoying Slitherlink puzzles lately, and thinking about publishing some variations. Below is a Slitherlink puzzle on a Hexagonal grid I made recently. This tiling makes it more complex in some ways, and easier in others.
More importantly, from my point of view, it’s round. Always a good thing in [...]

You connect horizontally or vertically adjacent dots to form a meandering path that forms a single loop or “Slitherlink.” The loop must not have any branches and [...]

I’m working on some new puzzles and thought I’d give you a preview…
For the kids, I’m adding a new collection of mazes in a variety of animal shapes, such as this elephant.
For the non-kids, I’m adding some new logic puzzles, based on my favorites from Nikoli, the Japanese publisher that popularized Sudoku. One of [...]

I was alerted to this group via Laughing Squid.
Faces in Places is an awesome flickr group that collects photosgraphs of those serendipitous faces that pop out at you from the world of inanimate objects.
I made a mosaic of all the images in the group, shown above. You can play with [...]

Via BoingBoing, MissMonster demonstrates how she made this excellent werewolf costume, using a lot of fake fur, hot glue, old gloves, and other stuff.
Check out MissMonster’s website to see some of her other great costumes & creations, as well.

A few recent excerpts from “The Daily Word,” a feature which I’ve been publishing the past few weeks mash.yahoo.com (in the module of the same name). Most of these were written by Mike Davis, who has an innate talent for lexicognition..

Craig Kaplan wrote to tell me about some newly available high-res scans of seven complete works of (my hero/obsession) Athanasius Kircher, made available by the Herzog August Bibliothek Wolfenbuttel.
UPDATE: I’ve corrected the above since my first post. The Bibliothek site is posting seven complete works, not just the illustrations excerpted on the bibliodyssey blog. [...]
