Round means roll, square doesn't roll. The space for a marking is limited hense a symbol. Anyway this is how I will change my glider. I never did figure out why I had such a bad day, but I assume somehow I was not getting O2 flow. I had a terrible headache. Checked the O2 system after I landed, realizing how many mistakes I made, and all was working. Flew the next day no problem. It was this same day that I had the wrong airport set for my final glide and even when I could see the airport I was aiming for way below me and my computer was telling me I was below final glide, I believed the computer until I had to decent for 4,000 AGL to land. Never had a stupid day in anything else I flew, but this was enough to get my attention and to constantly look for ways to improve my glider and anything that will make it safer.

I fresh idea. I shall paint a half dollar size green dot in the wheel down and locked position and a red square in the wheel retracted position. Less confusing than arrows or just color, square does not roll.

What happens when you forget what a square shape represents during the heat of the moment or someone else flies your glider?

The words UP and DOWN (or EXTENDED and RETRACTED) cannot be confused and since language is usually one of the last things one loses when your brain starts failing, it's probably the safest bet.
If my brain can't interpret UP/DOWN then in all likely hood I've already lost all my motor skills and a crash is inevitable.
