There is some gimmicks for this to be used for mobile Advertisement in the street at night.
May be fashion clothing at Disco! I think the power source is an issue.
If 160x120 LED means 19,200 LED, that each consume say each 50 mill watts power. That is a lot of power for lighting up 19K pieces of LEDs, he might need to change battery every 40 minutes. Unless he carry a big storage power, but his idea is niche and eye catching.
