"Both systems are connected to each other using the WiFi internet capabilities of the Nintendo DS system. The demo is incredibly simple: using a connected headphone/microphone piece, you speak into the microphone and listen with the earpiece. You essentially hold conversations using the Nintendo DS over the internet. The demo features a 3D Nintendo character on the upper screen, with a wavelength meter displayed on the lower screen. On my screen was Mario, on the other guy, Wario."
