Synchronization of effects across multiple devices using local, distributed control, and eliminating the need for central direction of the effects with the associated large bandwidth required. In one embodiment, each device stores data and instructions for creating its own effects. The devices periodically communicate with a host or each other to maintain synchronization, and compensate for any drift. This approach minimizes the use of bandwidth and battery power in the devices.

Synchronization of computer peripheral effects

Embodiments of the present invention provide programmable keys in a keyboard that provide the user with added functionalities and versatility to enhance the usage of the computer for game play or the like. In one embodiment, an input device for use with a computer comprises an input device housing; at least one input member disposed on the input device housing; and an auxiliary display connected to the input device housing, the auxiliary display being configured to display information received from the computer including images provided by the computer.

Embodiments of the invention achieve a very high success rate in multilayer peer-to-peer connection across firewalls and network address translators (NATs) using a single port on the local host. In one embodiment, a system of providing peer-to-peer connection comprises a plurality of host devices disposed behind corresponding NATs; and a plurality of STUN servers. Each host device includes a first socket bound to a first private port and a second socket bound to a second private port. Each host device sends a first STUN packet through the first socket to a first STUN server and a second group of STUN packets through the second socket to the STUN servers via public ports of the corresponding NAT. The STUN servers identify the public port numbers of the public ports. Each host device is configured to calculate a predicted public port number of the corresponding NAT for the second socket, based on the public port numbers of the public ports for the first socket and the second socket, the predicted public port number to be used for peer-to-peer connection between the second socket of the host device and other host devices.
