I agree this seems to fall in the category of "neat but seemingly useless" since it actually takes more power and effort to do a simple task.

But its more interesting to look at these "novelty" interaction patterns as stepping stones and building blocks to future interfaces. Most new things look novel and useless until someone cherry-picks the bits and pieces and makes something really revolutionary with them.

tl;dr More weird things, please!

Yep. I very much agree.

I'll attempt to make a prediction: gesture based and other natural computer interactions will become common-place by 2020, primarily in living room and personal robotics applications.

And right now, it is at the stage slightly ahead of the time when touch screens were first introduced: http://www.vintagecomputing.com/wp-content/images/retroscan/...
