Aerocool Turbine Series LED Fans
 

Airflow aside, probably the most unique feature is the number of blades: two separate layers of "interwoven" 8 blades for a total of 16. This doesn't seem to impact performance much either way, but the appearance is certainly novel. The model pictured above is the 3000 and has a transparent blue frame with 8 transparent blue blades. Between them are 8 chrome blades. You may also noticed that all of these fans have LEDs mounted around the perimeter.
