Jordan Rabet, know as smealum, describes himself as a "youngish game developer turned hacker" and has been showing off an upcoming WIP exploit that will enable users to run homebrew games on 3DS. The project has been in progress since August but it's only now he's revealed how it works, and that it all hinges on an old Ubi game called Cubic Ninja. Rabet announced this on Twitter:

Predictably, Nintendo has pulled the game from the eShop, while eBay prices have shot through the roof, topping out at nearly £80.
Rabet has been testing development with a version of Minecraft he's created called '3dscraft'. Someone who's played it says "the homebrew is in 3D. And it's actually pretty solid".
