I like everything that in Blue color, everything in Blue will get my attention more than other color. Actually blue hypnotize me. Take for instance the Scimitar Boomerang designed by Eric Darnell - the boomerang LED are in Blue, but I don’t want to talk about the color. Actually, this beautiful night shot was taken to show off the pretty oscillating pattern produced by the Scimitar’s embedded LEDS. Now Blue color make me tempted to get crafty like that Scimitar Boomerang.
