We've seen pictures of Sony's ODO Twirl N' Take, wind-up camera before. Here in Berlin, we actually had a chance to take this eco-friendly digicam for a spin. Ha, get it? We said spin to refer to this kinetic concept camera! Amazing.

ZMP's Miuro may have been doing the whole music-playing, rolling robot thing even before Sony's Rolly stole the spotlight, but it had the slight disadvantage of costing nearly $1,000. The company now looks to be changing that situation, however, with it teaming up with Sega Toys to release a slightly scaled-back but considerable cheaper version of the iPod dock, now dubbed the Music Robot ODO. Among other things, this one drops the built-in WiFi and camera of the Miuro, although it does hang onto the LCD that displays the ODO's "emotion" as it's dancing, and you do get a remote control to keep it from straying too far. No word on a release 'round these parts, naturally, but those in Japan can snag one for the not unreasonable cost of ¥15,540, or about $150.

Sony's showing off a whole range of new environmentally-friendly gear in Japan at the moment, all of which can be used without ever having to be plugged in for a recharge. One of the more interesting devices of the lot is the Spin N' Snap digital camera (pictured above), which you charge up simply by placing your fingers in the two holes (which also double as a viewfinder) and spinning it around a few times. Taking a slightly different but equally non-power-hungry route is the Crank N' Capture camera, which can also apparently capture video of some sort. Rounding out the line up are the Pull N' Play stereo headphones, the Push POWER Play device (apparently a viewer of some sort), which you charge by rolling it back and forth on a table, and the "Juice Box," which packs a fold out solar panel that can be used to charge your other devices. What's more, if we're reading the machine translation correctly, it appears that all the devices are made of re-used or recycled plastic. Unfortunately, there's no word on when or if any of them will actually be available, although you can check out a couple more pics courtesy of Impress after the break and plenty more at the link below.
