This is one of the most interesting news pieces ive seen in a long while for the Dreamcast and its regarding a wireless Dreamcast Gun, heres more details:

You may remember the LightConn wireless gun we revealed recently. It comes from hardware modder Chris Diaoglou (the man behind the other wireless peripherals currently available for the Dreamcast), and since the last update the device has undergone a rather impressive overhaul. The LightConn uses the same Bluetooth technology as the DreamConn wireless controller and the KeybConn wireless keyboard, and incorporates a pair of virtual VMUs.
