The recently-released Nintendo 3DS gaming system supports viewing of MPO image files, which means you can use it to view 3D photos created with 3DComposer. It's a long way from a 3D HDTV, but at $249.99 it's an interesting way to get into 3D viewing. You can also take 3D pictures with the 3DS, however its cameras are low quality, so using 3DComposer with another camera can yield better results.

How did you load your photos on the 3DS? Thanks

Put the MPO files on an SD card, and insert the SD card into the 3DS. The 3DS should be able to find and view them from there. Note that there are restrictions on MPO file and folder names that the 3DS can read. It should work to create a folder on your SD card named "DCIM\NNNLLLLL" and store the files in that folder as "LLLLNNNN.MPO", where each N is a number and each L is a letter.

Support for Nintendo 3DS is now added to the 3DMedia Gallery. If you are browsing the 3DMedia Gallery using Nintendo 3DS, clicking on the image (or click-and-hold) will display the 3D image directly on your device.
