In the season 7 episode (I can't remember what mit's called, but it's the one where Sam and Jacob/Selmak find the Ancient weapon in the mountain at Dakara), fast forward to the bit where Ba'al is talking to Sam and Jacob/Selmak as a hologram. Ba'al points to the Jacob/Selmak side of the device, the camera flicks around to look at Sam and Jacob/Selmak. He looks at Ba'al and reaches AROUND THE LAPTOP AND PRESSES ONE IN FRONT OF SAM!!! Does Jacob/Selmak need an eye check?
