What would be a good (as "easy" as possible) example of a Triangular (Non trivial) quasiHopf algebra? By trivial I mean the quasi strcture not to be trivial, but if the triangular structure is trivial it's ok (it's actally better for me)

Something like Drinfeld's twist of a group algebra will do the job.
