Under the hood it’s the same Blink engine that power’s the regular Opera browser (and Chrome) but I really like the interface on this experiment. It’s described as being a “concept browser”, much like a “concept car”, which is a nice way of framing experiments like this. More concept browsers please!
I keep coming back to this recipe. Simple and delicious.
