Fun fact: this was originally done in Square's Card Case (by Robert Andersen, who coincidentally used to work at Apple). The hologram on the credit card used to change with the angle of the phone.
In-app hologram when you edit your credit card. Unfortunately this is not in the shipping build of Pay with Square, but it was there in Card Case (and was epic!).
I design things. I'm particularly interested in iOS projects. Have worked with many, many YC companies: Posterous, Mixpanel, Greplin, Talkbin, Parse, and more.
I'm 17, and drive a manual. My parents thought I was crazy when I said I wanted to only drive manual, and I've noticed that at my school my vehicle is one of probably 5 cars (out of >100) in our lot that's a stick. When I ask friends why they don't drive stick, they say they simply don't want to deal with the hassle of it. Enthusiasts are few and far between…
