the only machine that turns a blank wall into someone else's dream.
means A device that throws an enlarged image of pictures, film, or digital files onto a screen or wall by casting light through or off them.
from From Latin 'proicere,' to throw forth — 'pro-' (forward) plus 'iacere' (to throw), the same root that hurls us 'projectile' and 'eject.' A projector is literally a thrower-forth of light, and for centuries 'project' simply meant to cast something outward before it ever meant a plan or a glowing image on a wall.
