I just came across the Tinkerlog store, which is selling a programmable LED. I love the minimal design – no PCB, just a few components soldered together freeform – and the photo on the shop site is beautiful too.
I read in Wikipedia the other day that LEDs can also be used as light sensors, so perhaps further design simplification is possible.
Safari 4 good:
they moved the tabs off of the window title bar
bad:
I still can’t change default search engine.
The latter is really annoying me. Since I am working in Microsoft Live Search, my opinion is not completely unbiased, but I would really like to be able to change my default search engine from google.com to bing.com. Every other search engine allows this, so why not Safari? To compound matters, Safari does not have a very widely used plugin system, and I have not found an authoritative plugin which allows me to change my search engine.
