Virtual reality in a cereal box

Has anyone else tried this yet?
I've been checking the super markets and the local countdown had some stock the other day. $7 for the pack.

Thought we could share tips and experiences here.

I've built google cardboard 2.0 before this, a couple of months ago. It was good, but was difficult to find good build tips (what gauge cardboard is most suited?, instructions were MIA on googles website when I was looking, might have been between updates).
The hard part in NZ is getting the lenses (BOLt VR solves this thanks!). I couldn't wait to order from overseas, so made my own following this tutorial...

Watch "Making of LENSES for Google cardboard" on YouTube

The experience using an iPhone 6 plus was excellent.

The Bolt VR is in many ways an improvement/refinement of cardboard. It assembles very cleanly and is a bit easier thanks to its slightly simplified construction. Using their own suitably gauged cardboard for their design means it comes together well with just a few bits of sticky-tape.

Getting plastic lenses is the real benefit, these were much clearer than my ghetto plastic bottle filled with water lenses, however Ive found sometimes this is a disadvantage, with jagged edges being more aparent. The blurriness of my home made lenses was better than you might expect, and had the effect of "anti-aliasing".

Bolt VR also seems designed for a slightly smaller head, nothing the scissors can't remedy. I guess it's designed with kids in mind. The lenses are almost too close together for my liking, this is something more difficult to remedy, because the two lenses are one piece of plastic (this has the advantage of not requiring 'tabs' to hold them in place). I'm still not sure the focal length is correct for a large (5.5 inch) phablet, and that I'm seeing the full image.

One pitfall I found too late...several of the BOLT app "experiences" have to be unlocked via QR codes (to sell more cereal I suppose), and somehow I chopped my code during construction, maybe we can share QR codes in this thread.

As for other apps, I've checked out about 20 for iPhone, and will recommend the best below, haven't tried Android apps yet, but there should be a wider selection with this being a Google thing...

Best iOS VR apps:
Rollercoaster - excellent effect, good graphics, perfect demo for new people,
In mind VR - the closest thing to a complete game experience, excellent effect, good graphics
Dive City coaster - very fast, good effect, 2nd best Rollercoaster.
The Height - 1st person maze game, good graphics, but difficult, frustrating, maybe too fast
Moorente - duck shooting, very tech demo beta feeling.
NG Bolt - the bolt vr app
Google Cardboard - Googles famous app for iOS is a must have.

Alright Apps:
Offshore VR - A promo app, with a reasonable effect, shame you 'teleport' around the place, the helicopter ride in at the beginning is a highlight.
Block Amok - An angry birds in VR experience.
Sharks VR - Like an underwater demo, its an average demo that won't hold any interest for more than 30 seconds.
Crazy Swing VR - Cant remember this one, will have to try again.
Occupation VR - This is interesting it is an open world (multiplayer?) sandbox game like day-z. But when i played nothing much was happening - too boring.
Jurassic Virtual Reality - Low res, largely static, the odd dino running around - worth a quick explore, but becomes boring.
Air Races - Fly around really fast. Reasonable effect, average/poor graphics - boring.
VR Mojo Orbulus - Scrolling images
Space Slider VR - Challenging game, average graphics.

Worst iOS Apps (Avoid these)
VisitVR - Shows mildly scrolling stereoscopic images.
Stereoscopic Tunnel - Just a 3d Tunnel
Timpaan - Some 3d house
Dreamizer 3D - Some 3d house with interactive elements...
