Walkman Museum

Several decades before the invention of the iPod, the audio technical wonder of the age was the personal cassette player – given the generic name Walkman after Sony's bestselling model. Rather than MP3s, Walkmans held cassette tapes – a maximum of 120 minutes of music being a far cry from the thousands of hours of albums people now carry around in their pockets without thought. Here, the Walkman in all its clunky wonder is celebrated with photographs and ads of all the bestselling models, the latter usually featuring users involved in rollerskating, skydiving or staring in excited awe – standard activities in the early-80s. Now collectors' items, the museum also houses a value guide and forum so you to can hunt down an Aiwa HS-PO2 just like Marty McFly.

Big Think

Can gay rights boost economic prosperity? Should information have an expiration date? Is the internet mankind's most profound achievement? These questions and many others are discussed at this site dedicated to thoughts, opinions, ideas and imagination. Like most good things associated with clever stuff that's not offputtingly high-brow, it's no surprise to see Stephen Fry involved. Here, he's elucidating his favourite philosophers and the importance of unbelief: "If you assume there's no afterlife," he says, "you'll likely have a fuller, more interesting life." Other video shorts include professor of Behavioral Economics, Dan Ariely (pictured), explaining the "Ikea effect" and a paleontologist saying that the chances of no other life existing beyond Earth as "near zero". Elsewhere, a bunch of experts imagine life in 2050, while the blogs contain some intriguing articles on the sex appeal of spies and the medical downside of the vuvuzela.
