Small devices used to display a modicum of pictures in a “frame” style casing. In essence, they replace photo frames in the sense of “displaying many more pictures than just one”. It appears that they almost always run a variant of Linux (or Android), paired with some ARM or MIPS CPU.

remount /system as read/write

While little detail has been put into this, it is possible to get into a root ADB shell on these. Thus, there is potential.

Basic framebuffer support is now included

A simple Linux kernel port. Apparently this thing communicates through phone to the CPU? Very odd. Kernel 2.4.19 + a custom patch, which enables the flash chips and the framebuffer. Maybe this could be developed into something more? Although, 4MB of DRAM is paltry.

There are several included demos to try. type any of the following on the command line

Surprisingly overpowered for a little frame. Even the 8MB SDRAM can be upgraded to 32 or 64MB. Full framebuffer access. Capable of running little programs, which could maybe lead to more practical/functional capabilities? Most interesting programs require a Wii Remote paired to the Bluetooth this thing has. Can also run Doom, but that needs swap/upgrade of RAM.
