the straw view

you can only see through a small area. this is a wall about 4'x5' of drinking straws. standard ~0.25" diameter clear straws. no bend.

 

moving the wind tunnel.

each side of wind tunnel is six standard box fans. then a bank of straws to collimate the air flow. window on one side. 2 x4 and plywood framing. low tech but functional.
