Optimus Tactus does not have physical keys, which means there are no restrictions on their shape and size. Any part of the keyboard surface can be programmed to perform any function or to display any images. (artlebedev.com)

We are all familiar with the simple ways of tiling the plane by equilateral triangles, squares, or hexagons. These are the three regular tilings: each is made up of identical copies of a regular polygon — a shape whose sides all have the same length and angles between them — and adjacent tiles share whole edges, that is, we never have part of a tile’s edge overlapping part of another tile’s edge.

In this collection of tilings by regular polygons the number five is conspicuously absent. Why did I not mention a regular tiling by pentagons? It turns out that no such tiling can exist, and it’s not too hard to see why: a regular pentagon has five interior angles of 108°. If we try to place pentagons around a point, we find that three must leave a gap — because 3 × 108 = 324, which is less than the 360° of the full circle — and four must overlap — because 4 × 108 = 432, which is more than the 360° of the circle (plus.maths.org)

The fact that Radiohead debuted its latest album online and Madonna defected from Warner Bros. to Live Nation, a concert promoter, is held to signal the end of the music business as we know it. Actually, these are just two examples of how musicians are increasingly able to work outside of the traditional label relationship. There is no one single way of doing business these days. There are, in fact, six viable models by my count. That variety is good for artists; it gives them more ways to get paid and make a living. And it’s good for audiences, too, who will have more — and more interesting — music to listen to. Let’s step back and get some perspective. (Wired)

levelHead is a spatial memory game by Julian Oliver. It uses a cube – with an image on each face – as its only interface.

It uses a Sony EyeToy camera to capture the image and a screen to present the computed result.

‘Inside’ the cube are six rooms, each of which are logically connected by a network of doors. By tilting the cube you lead a character around the rooms.

Some doors lead nowhere and will send you back to the beginning. You have just 120 seconds to find the exit of each cube and move to the next.

There are five cubes (levels) in total and just as you imagine, the traps become increasingly difficult to avoid. (julianoliver.com)

In a friendly, high-speed presentation, Will Wright demos his newest game, Spore, which promises to dazzle users even more than his previous masterpieces. Here Wright encourages users to create not households, as in The Sims, or cities, as in SimCity, but the entire universe, from single-celled life forms to galactic physics. While guiding us through his mesmerizing beta, Wright shares his thoughts on Montessori schools, Darwinian theory and long-term thinking, emphasizing, throughout, that Spore is not so much a game as an opportunity for discovery — “an imagination amplifier.” (ted.com)
