Amazon has a good deal on the first year of Make Magazine, all four issues for $38, this is a decent price considering a single issue goes for $15 . Compared with most other magazines, there are very few ads in Make, and it's packed with a wide range of projects, so it's more like a book than a periodical. Well worth the price for the boxed set.

If you haven't seen this video yet, The Way Things Go is worth taking a look at. It's a thirty minute long Goldbergesque set-up using chemical reactions, fireworks, water, common household objects, rigged contraptions and much more in a domino type sequence of continuous motion. Four out of five stars.

For anyone interested in tools who might like a book on the subject, I highly recommend The Dictionary of American Hand Tools: A Pictorial Synopsis. With over 4500 illustrations, it's a great reference and is the first book that I turn to when I find an unidentified tool. Btw, I don't make any money on links from this site.
