The ability of the iPad 2 to mirror its screen to a TV is a neat one, but it has a downside: it requires a cord. Not so with this hack that allowed the iPad to share its screen wirelessly.
Eric Govoruhk and Kelly McAteer took it upon themselves to create this solution, which involves a wireless HDMI transmitter and a USB battery pack. Nothing too complicated here, but it does require a bit of elbow grease. The countdown now begins for a hardware company to release their own version of this, which seems inevitable.
