Most Haunted use Star Trek Tricoder to hunt ghosts
Spot the difference...
On the left is a picture from an old episode of "Most Haunted" on Living TV (which my wife was watching, not me, honest). They claim it is one of the devices they use to find ghosts, etc.
On the right is a screen shot of the Star Trek tricorder iPad app.
Clearly one was based on the other. The one on the left looks like a real thing (i.e. real lights) not the screen of something like that on the iPad.
I wonder what the device is, and if it is real or a toy...
Update: Found it! Most Haunted use a Star Trek Tricorder to find ghosts. Ha!
No wonder they did not show the bottom of the device on screen :-)
