There's nothing new about the dimension of smell in video games — US company ScentSciences has made a business out of it for a couple of years with the ScentScape unit.
Twisting the concept slightly, fragrance and candle makers have made products designed to evoke the smell of games and their characters.
But the whiff of hot, buttery popcorn is another prospect entirely and Pop Secret knows this. That's why it's created the Pop Dongle, which it says is the first ever scented mobile game experience.
The dongle, a manic looking character that supposedly resembles a bunch of popcorn, plugs into your phone and emits the delicious smell as you play the iOS game Poptopia. The makers promise your nostrils will rejoice.
