see similar loom in action here:
Small rigid heddle.
Designed for backstrap weaving but can also be rigged up to a small table loom.
This one is great to weave belts and bands. And since it is small you generally wont need anything else but this, a shuttle and some yarn.
Totally portable, behold the pocket backstrap! unless you are wearing skinny jeans then it might not fit.
