I remember back in 2009 I really liked their coffee machine icon. I emailed the devs, they referred me to some design studio, and then to my surprise they replied and said that it's Francis Francis X1. Now I'm looking at it in my home office.
Sad that they got acquired because it was just fascinating what they were doing, even if I was never going to use it.
SproutCore 2.0 became Ember.js 1.0, but I don't know if Apple are still using it.
No idea if they ever did anything with it!
I'm on the outside, but best I can tell:
- You're thinking of a UI design tool called "Ninja"
- Google purchased Motorola Mobility and the Ninja project got cancelled
- Google launched Google Web Designer, that basically had an almost identical UI. As far as I can tell the internals are different, but probably shared some code or at least design work.
