Mimoco, creators of the Mimobot design-led USB flash drives, is celebrating its fifth anniversary with the introduction of new designs, exclusive 'bots, and the reissue of original characters. Over the years the company has created drive in collaboration with artists in the designer vinyl toy scene, as well as devices based on licences from the likes of Star Wars and Hello Kitty.

There will be a series of launches over the next six weeks. First off today is the re-release of four original limited-edition Core Series characters in new colours. Isadore, the very first Mimobot character to be released five years ago, returns in a new green colour variant (below).

Isadore is joined by a blue Fairybit, a purple Swirl, and a fourth generation black RayD81. All are now available in 2GB to 16GB capacities.

"Our fans are extremely passionate about our 'bots, and part of bringing back the old favorites is to offer our loyal fans the MIMOBOT drives that started it all," says founder Evan Blaustein. "Celebrating our five-year anniversary is a milestone event for us and we're stoked for what's in store on the MIMOBOT horizon for this and many seasons to come."

Other new Mimobot flash drives to be unveiled over the summer include Empire Strikes Back and Hello Kitty's friends, plus a new Artist Series Mimobot by Hong Kong illustrator and designer toy artist, Kenny Wong. More Core Series characters and Star Wars models will also be announced.

Mimoco has also teamed up with Infectious.com, a maker of electronics skins and skateboard decks for the Unmasked Design Challenge competition where artists and graphic designers are asked to to create their best 'Unmasked' Mimobot characters. The submission period ends July 15th.
