Today I came across this tweet from @StarbucksUK:

I really like this clever use of the false frame illusion and I realised, how often I tend to “think” in frames and boxes. I suppose writing CSS and dealing with the box model for a couple of years somehow clouds the view for design delighters like this one. I’ll have to remind myself not to think in boxes and frames all the time. At least that’s what I learnt today.
