Holographic fans and volumetric units that hang an image in the air above a counter. Worth knowing before buying: the effect depends on a dark background behind it, so a fan in a bright window is money spent on something nobody can see.
A spinning LED fan or volumetric unit that makes a logo or product appear to float in mid-air — the shelf covers both fan-style and volumetric formats.
No — the image forms in open air and reads with the naked eye; it looks strongest in a darker room or a shaded corner of the floor.
A rotating logo, product render or short animation, loaded onto the unit itself; a hologram projector accepts set file formats, and we'll confirm those per model.
A single 42 cm fan suits a logo or one product, and tiling several fans builds a larger image — tell us the wall size and we'll spec the array.
