Pick-Os Builder
Created in Javascript, a simple building simulator using text character O as building blocks.
Plan to use darkening, bluening color to help indicate depth, as well as size and position.
I'm observing with this default font that a 50px O renders as 35 pixels across.

some maths - assume closest object is a fixed distance, or 'center'?
render order will relate to depth
if 2d coord, with 20 unit space from center to virtual viewpoint, and an object at -5 units x, -3 units y, then need to render it larger and lefter
distance from vv to obj = (20-3)^2 + 5*5 then sqrt = 17.72
so this object would be 20/17.72 bigger than one at origin
projecting the object back to the origin row,
