Hue Optical Illusion Arjen Goldschmidt has sent in what appears to be the best (proof-endorsed) color optical illusion I have seen up to date! Below examples showcase embedded lines of seemingly different colors. The reason they look different is because our brain judges the color of an object by comparing it to surrounding colors. So without us even knowing it, in first example, our brains compare the flowing red stripes to the yellow stripes, forcing us to think they are orange. The blue stripes make the red ones appear much darker -almost purple, even though they are exactly the same color! This is just one of the examples why you cannot trust what you see even with your own eyes.
Laser is produced by a living cell 13 June 2011Last updated at 01:42 By Jason Palmer Science and technology reporter, BBC News The single-cell lasers were less than 20 millionths of a metre across A single living cell has been coaxed into producing laser light, researchers report in Nature Photonics. Aleph Null: Color Music Jim Andrews: concept, programming, design Jan Odvárko: color-picker Thanks to Regina Célia Pinto, David Jhave Johnston, Ted Warnell, Maarten van Emden, Christine Wilks of JSArt, and the British and Irish Poets List--especially David Bircumshaw--for feedback during dev. Aleph Null is my first piece with the new HTML 5 canvas tag which requires no plugins and works in all modern browsers, including mobile phones. It's exciting to have such a canvas to work/play with in a public technology that is not at the mercy of a corporation's business plan or its continued existence.
Cognitive bias Some cognitive biases are presumably adaptive. Cognitive biases may lead to more effective actions in a given context. Furthermore, cognitive biases enable faster decisions when timeliness is more valuable than accuracy, as illustrated in heuristics. Other cognitive biases are a "by-product" of human processing limitations, resulting from a lack of appropriate mental mechanisms (bounded rationality), or simply from a limited capacity for information processing. A continually evolving list of cognitive biases has been identified over the last six decades of research on human judgment and decision-making in cognitive science, social psychology, and behavioral economics. Kahneman and Tversky (1996) argue that cognitive biases have efficient practical implications for areas including clinical judgment, entrepreneurship, finance, and management. Overview

Lilac chaser Stare at the center cross for at least 30 seconds to experience the three phenomena of the illusion A gap running around the circle of lilac discs;A green disc running around the circle of lilac discs in place of the gap;The green disc running around on the grey background, with the lilac discs having disappeared in sequence. The chaser effect results from the phi phenomenon illusion, combined with an afterimage effect in which an opposite, complementary, colour—green—appears when each lilac spot disappears (if the discs were blue, one would see yellow), and Troxler's fading of the lilac discs. History The illusion was created by Jeremy Hinton some time before 2005.
Kowloon Walled City History Military outpost Lung Tsun Stone Bridge and Lung Tsun Pavilion (Pavilion for Greeting Officials) of Kowloon Walled City in 1898. The history of the Walled City can be traced back to the Song Dynasty (960–1279), when an outpost was set up to manage the trade of salt. Little took place for hundreds of years afterward, although 30 guards were stationed there in 1668. A small coastal fort was established around 1810. In 1842, during Qing Emperor Daoguang's reign, Hong Kong Island was ceded to Britain by the Treaty of Nanjing. LEGO Optical Illusion Mosaic This is what you get when you combine LEGO and optical illusions. Main effect – the circle made of the studs, produces the appearance of curved pieces. However, the design can appear very different depending on the angle it’s viewed from. I’m still discovering surprising patterns in it. If you still got some LEGO brick laying around, try and reproduce some of your favourite old school illusions and we’ll certainly make them pubic public!
