The release of the Square Payment System is here, allowing you to use your iPhone as a credit card reader. Square will also support the iPad and Android devices. The app is already available in Apple’s App Store and the credit card reader is free to those who sign up.

The service isn’t free, however. Retailers will have to pay fees that start at 2.75 percent, as well as a 15 cent surcharge. But the setup cost is probably cheaper than other options out there.

Here’s something you don’t see everyday. A square Motorola handset from squaresville. This oddity is apparently running Android 2.1 with MOTOBLUR and is a QWERTY slider.

We have practically no details aside from the image itself. We know that it’s square. That much is obvious. We will hopefully learn more soon. And when we do, we will let you know. Any of you want a square phone?

Zumreed Dreams Square headphones feature a frequency response of 20-20,000Hz with 32Ohm of impedance, and a 3.5mm gold-plated stereo mini plug, plus they look nice and retro, even if they are square. They weigh 210grams, combining a simple leather headband with square earpads.

They come in six different colors for just $69.99. If you are looking for smething different in a pair of headphones, the Zumreed Dreams Square headphones are worth a shot for casual listening.

Art Lebedev Studios has introduced it’s Luxofor traffic light prototype, with square lenses that are lit up by superbright diodes to make it them more visible to drivers and pedestrians. As usual, a million of you have slapped your head and asked “Why didn’t I think of that?”

The square light fills up the same space taken up by a round lens more completely. It’s just a concept right now, but the Art Lebedev team wants to cooperation with road safety councils and local authorities to improve and design road markings and signs. What will the team think of next?
