I was trying to figure out how to quantify glare the other day and found this:

Unified Glare Rating UGR basic explanation.

Pretty clear, right? If not, just buy the poster.

A more useful page for the laity, perhaps, is this explanation of light diffusers:

Light Diffusion and Light Diffuser Types

There are more easy-to-follow explanations on the Fusion Optix blog, but sadly it appears they’ve stopped updating it.

The sound of your voice splattered on a wall with light, by¬†Chevalvert, 2roqs, Polygraphik, and Splank. [If you can’t tell, those are names of French studios.]

A pretty visualization. I like the illusion of slowing audio down so that you can see it transmitted along a cable.

Another major breakthrough in light fixture technology: ultra-thin OLED. Some nice designs at Blackbody, but I think it can go much further.

Crayola Light Marker for iPad lets you ‘paint in the air’ for $29.99 | The Verge.

This is ridiculous on several levels. Here are two.

#1: The pen is (probably) an infrared LED and can be made for $5.

#2: Why is it better to draw on an iPad while swinging your hand in the air?

Markers on paper are fun. And they’re especially fun for young kids who are just getting started with drawing. Putting your hands on a pen and making it move on paper is an invaluable experience–a necessary one, in fact. The brain learns by drawing, and the tangible part of drawing is crucial to that learning. An air pen is no better than an air guitar. Maybe fun for a few minutes, but ultimately a waste of time and a dissatisfying experience.
