Design Appreciation

I feel that this is a good design for a fan as it does not require as much cleaning as a normal fan, as it does not have blades and a cover.

I feel that this is a good design as it enables blind people to find out what keys are meant for what purpose.

I feel that this is a bad idea as it wastes a lot of materials which makes it not environmentally friendly and also takes up a lot of space.

This is a bad design as it is very misleading. If u follow the arrow u would have to ride on the road or run the risk of hitting other cyclists.
