Silly as this product is, as a kid I always wished for something like this to up the immersiveness of video games. Maybe it would be doubly effective now with VR.

Getting it in a reasonable form factor and some practical issues (stinking up the house) seem like roadblocks, but I wouldn't be surprised to see something like this come back around, focused on gaming.

I was always thinking about cinemas - especially since I first saw a "4D movie", in which they augment the usual 3D movie experience with tactile effects generators - air blowing at you to simulate wind, small amounts of water suddenly being sprayed at you, etc. It really added to the immersiveness of what you were watching, and the only thing lacking was smell effects.

You would just need the smell of blood, gunpowder, and charred meat.
