Tom Wujec studies team dynamics and puts on workshops around team building and prepares groups to solve large and complex problems. During his workshops he gives teams The Marshmallow Challenge, an 18 minute challenge to build the tallest structure from a few items including spaghetti and marshmallows. Interestingly, kindergarteners produce some of the tallest structures. Tom chalks up their success to iterative prototyping and trying lots of ideas. On the contrary, business school students do the worst.

Seth Priebatsch, Chief Ninja and CEO of SCVNGR, a mobile start-up looking to build a game layer on top of the real world. In this TEDx Boston talk, Seth talks about the fact that the social layer (think Facebook) is now complete, and that the next step is creating a game layer. Games already exist in today’s world, be it credit card and frequent flyer miles, or the happy hour at your local bar, but they are not very well designed. Seth believes we can do better. Seth advocates using game dynamics for good, be it getting people to take their medicine on time, reconsidering the grading systems in schools, and organizing communities around common goals.

Ji Lee, Creative Director at Google, speaks at the 99% conference about his personal endeavor in 2002 to break out of the creative constraints of his advertising job by creating his own art project. Ji’s ad-spoofing Bubble Project entailed printing out stickers in the shape of word bubbles and sticking them on advertisements all around New York City. Ji would return later to document what people would write into the bubbles. Amusing, political, and esoteric, the bubbles were a hit and spawned campaigns by others. Ji now advocates for using personal projects to provide an outlet for personal creative freedom, create platforms for others to collaborate, meet new people, and to learn new skills.

David McCandless, award winning designer, writer, and author, speaks at TED on his passion for exploring data and creating meaningful visualizations that convey information in the form of a story. With a plethora of examples from his latest book, Information Is Beautiful, the talk is both facinating and inspiring. In one example he displays the carbon output from the Icelandic volcano that grounded thousands of flights over Europe in 2010. By comparing the carbon output that those flights would have produced themselves, the eruption was the first carbon-neutral volcanic event the world has seen. David posts his visualizations on his website and it is worth diving in to take a look.

James Archer, Managing Director at Forty (a design and marketing consultancy), posted a great webcast explaining how people make purchasing decisions and gives some very practical advice for designing websites seeking new users and customers. Potential customers fall into four different categories (called Decision Modes): spontaneous, competitive, humanistic, and methodical. The categorization depends on two scales. The first, fast or slow, and the second, logical or emotional. By taking into account the information each of these consumer types look for, you can ensure success in communicating the value proposition and convert more customers.

Tan Le, head of Emotiv Systems talks at TED about their creation of the EPOC, a brainwave reading headset. The EPOC has won a 2010 Red Dot Award for design, and uses new algorithms to read the brainwaves of any individual. Unlike previous brainwave reading headsets which take a long time to set up and cost on the order of tens of thousands of dollars, the EPOC is available now for $299 on the Emotiv website. The applications for the device are incredibly diverse and endless as it provides the ability to control any digital device with one’s mind. Emotiv is currently seeking developers and researchers to expand upon the platform and come up with new applications for the device to usher in all new and exciting human computer interactions.
