"Atomic" means trademarked by a company that used to use that name in the 50's
to describe and identify a line toys it put in its breakfast cereal boxes.
The rights are now owned by an IP scavenging company which is trying to sell
them for stock in another IP scavenger with more money left, so be careful.
There's also some related talk of a patent on a method of using semiotic elements
in association with the distribution of digital generic products to make them
distinguishable for any business purpose whatever. IP principles established with
corn flakes and decoder rings are thought to translate perfectly to the digital
domain of FOSS distros including anything toy-like.
