Apple is doing a new trick at its flagship San Francisco and New York Stores to show off the benefits of 3D Touch on the iPhone 6s and 6s Plus. A video from Grate App (below) shows the phones rigged up to a table that’s actually a very large display.
When you press on the iPhone’s swimming fish screen-saver, it creates ripples in the screen around the phone, which vary in size depending on how hard you press. (The table itself doesn’t appear to be force-sensitive, but rather just takes 3D Touch input from the phones.)
It’s a clever way to tout an iPhone 8 feature that’s a bit hard to grok, but there’s no word on whether you’ll see it in any other stores.
