;; set some pixels
(set-simple! :state/ledbeere-frame [:green :blue])
(set-simple! :state/ledbeere-frame (cycle (segments [[1 :red] [10 :yellow]])))

;; using frame-generators
(set-simple! :state/ledbeere-frame (resolve-generator {:type :generator/cycled
							   :chain [:generator/segments]
						   :nr+colors [[1 :blue] [10 :yellow]]}))
