Tobi Kim has an ambitious concept. A universal remote that attaches to you jacket button. The Multi-Chalk is supposed to replace and control all your devices.
I personally have a few gripes about this. First, what if you have a zipper jacket? Next, who would want to control all the devices in an place where a jacket is needed? Lastly, why would you want to have to look at you belly to see what you are doing?
Please note this concept is not actually functioning, nor can imagine it working in the future. I deem this one a waste of time.
