10 Inch 16:9 Flexible 1080p OLED Panel -> HDMI Daughter Board -> HDMI Cord -> Graphics Card ($450 ish for panel and parts to make HDMI daughter board, and power supply).
Wide brim baseball cap $15ish + Zipties and Duct Tape ($9)
put it all together and you have a 10 Inch 1080p ( .89:1 display) (1:1 would be retina display) curved to the brim of the hat, zip tie the daughter board to the top of the hat, duct tape everything else.
oops forgot the long HDMI cable to run from PC to hat. ($30)
from there, you mount track IR clip to the hat, and reset track IR to 1:1 movement ratio, and your gold.
