When I bought Urban Decay's Book Of Shadows IV with all the gadgets and QR codes, I was a bit annoyed that I couldn't use any of them. You see at the time I didn't own a smart phone, so all of that technology was lost on me. Annoyingly I also couldn't watch the tutorial videos it came with (quite a big change from the booklet with the second Book Of Shadows), but finally even I own a smart phone, so I thought I'd share the links to these tutorials with you in case there are still people out there who otherwise couldn't watch them.
The palette came with a card with 5 QR codes that you can scan in with your phone and it takes you to the Urban Decay website where you can watch the tutorials. Of course you can do that on your computer too, so here are the links for the 5 looks. Enjoy!
