It's really neat thinking that we're living in a day and age where it's totally A-OK to design an entire toy line around the assumption that kids have smartphones. The Angry Birds series seems to be ripping it up with their line of telepods which have been really hard to come by in my area, and this new HolograFX toy seems even cooler. Check out the demo video:
The HolograFX kit sells for $24.99 on Amazon and if their site is to be believed, you should be able to find the setup locally at "regular toy shops." The kit itself appears to be just the set of mirrors you need to create the holographic illusion, somewhat similar to the old Time Traveler arcade machine.
Anyway, HolograFX randomly popped up on my radar this morning, and I'm pretty sure this is something that my kid self would've been obsessed with, so, here you go. If nothing else, HolograFX is no more gimmicky than all those Spy Gear gadgets that barely do anything.
