Molecular Expressions: Science, Optics and You - Secret Worlds: The Universe Within - Interactive Java Tutorial
This version of the old powers of 10 demo goes from 10 million light years (10**23 meters) to 100 attometers (10 ** -16). It stops at quarks -- too bad -- it would be interesting to continue to the Planck length.
I'm struck again by how self-similar the views are until we drop down to a terrestrial scale.

how to add an Airport express to extend (WDS) an Airport Extreme network
macosxhints - Airport Express WDS with third party NAT / DHCP: "This hint describes how to add an Airport express to extend (WDS) an Airport Extreme network that uses some other (wired) host (e.g. a broadband router) to provide DHCP and NAT. The Airport Express Assistant will let you set up WDS automatically, but it insists that the master airport uses NAT and DHCP, and has a static IP address, which means you have to form a separate subnet for the wireless portion of your network.

Exif Jpeg header parser and thumbnail remover (OS X)
Exif Jpeg header parser and thumbnail remover
The only program I've heard of that can attach an EXIF header to an existing JPEG. I wonder if it can fix duplicate rotation tags!?
They reference this article -- one of the very few anywhere on the EXIF file format
http://park2.wakwak.com/~tsuruzoh/Computer/Digicams/exif-e.html
I liked the explanation of the EXIF orientation tag from the reference:
The orientation of the camera relative to the scene, when the image was captured. The relation of the '0th row' and '0th column' to visual position is shown as right.
0x0112 unsigned short 1
Value 0th Row 0th Column

2 top right side
3 bottom right side
4 bottom left side
5 left side top
6 right side top
7 right side bottom
8 left side bottom

ZVOX: powered speaker units -- legacy of the iPod
ZVOX Stereo and Home Theater Surround Sound System For Your TV, PC, CD or MP3 Player - Built-In Speakers, Amplifier and Powered Subwoofer!
This looks like a product niche with a future. The amplifier and speakers are an integrated compact unit. Clearly the expected input is an iPod or other hard drive device (cell phone etc).
A bit big for the kitchen unfortunately.
