Magna-tile-tastic

Today, Heather recommends a toy that her brood never tires of:

Magna-tiles may very well be the best toy purchase I have ever made. My 7-year-old and 4-year-old triplets never get bored with them, and, well, neither do I. We purchased the 100 piece translucent set that includes square and triangular tiles in a variety of sizes. The tiles attract on all sides and in all combinations, helping children move easily from two-dimensional to three-dimensional creations.
The tiles truly are unbreakable as advertised (and believe me, my triplets in particular have put them to the test!) and offer a fun way to teach spatial relationships and inspire creativity. My kids proudly show off their creations -- rocket ships, boats, airplanes, mazes for their Hexbugs, houses, towers, stages for their talent shows, ice cream cones, etc. -- and have just as much fun knocking them down before building again.

The only downside of the tiles is that they are expensive, but we've found them to be worth every penny and then some. We love the tiles so much that we're looking to get another set this year, likely the non-translucent version.
