link Nanex - Market Crop Circle Of The Day

"The common theme with the charts shown on this page is they are obviously all generated in code and are algorithmic. Some demonstrate bizarre price or size cycling, some demonstrate large burst of quotes in extremely short time frames and some will demonstrate both. In most cases these sequences are from a single exchange with no other exchange quoting in the same time frame."

link Market Data Firm Spots the Tracks of Bizarre Robot Traders (The Atlantic, 4.8.2010)

"The trading bots visualized in the stock charts in this story aren't doing anything that could be construed to help the market. Unknown entities for unknown reasons are sending thousands of orders a second through the electronic stock exchanges with no intent to actually trade. Often, the buy or sell prices that they are offering are so far from the market price that there's no way they'd ever be part of a trade. The bots sketch out odd patterns with their orders, leaving patterns in the data that are largely invisible to market participants."

link Bengt Sjölén, Adam Somlai Fischer, Usman Haque: Wifi Camera

The Wifi Camera is a camera that takes "pictures" of spaces illuminated by wifi in much the same way that a traditional camera takes pictures of spaces illuminated by visible light. The camera reveals the electromagnetic space of our devices and the shadows that we create within such spaces, in particular our wifi networks (..) With the camera we can take real time "photos" of wifi (and we're working towards having video too). These show how our physical structures are illuminated by this particular electromagnetic phenomenon and we are even able to see the shadows that our bodies cast within such "hertzian" spaces. Radio waves at wifi's wavelength behave similar to light in that they are reflected off almost all solid objects to varying degrees, just as when we see colors we see the light from a light source being reflected off an object into our eyes. And, just as with light, some materials are opaque and some materials are more or less transparent.

link The ghost in the field

This image is a photographic mapping of the readable volume of a radio field from an RFID reader. The black component in the image is an RFID reader, similar to the component inside the yellow part of the oyster card reader. The camera has been fixed in its position and the reader photographed. Using a tag connected to an LED we paint in the edges of the readable volume with a long exposure and animate them to show the form.

link Visual Trace Route Tool

The visual trace route tool displays the path Internet packets traverse to reach a specified destination. The tool works by identifying the IP addresses of each hop along the way to the destination network address. The estimated geophysical location of each hop is identified using MaxMind's GeoIP database.

link Scientists extract images directly from brain

According to the researchers, further development of the technology may soon make it possible to view other people’s dreams while they sleep. (..) The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Using a functional magnetic resonance imaging (fMRI) machine, the researchers first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes. Subjects were shown 400 random 10 x 10 pixel black-and-white images for a period of 12 seconds each. While the fMRI machine monitored the changes in brain activity, a computer crunched the data and learned to associate the various changes in brain activity with the different image designs.
