  Much research has been done around creating multisensory ideation and
prototyping tools. We relate our own multisensory tool, the Loaded Dice, to
this domain. We briefly explain what sensing and actuating possibilities the
Loaded Dice already have (including thermal sensations), and how they are
methodically embedded in workshops using an extended interaction vocabulary to
characterize and ideate multisensory experiences. We briefly ponder simple
technical ways to add smell as an output modality, and discuss why and how
smell capabilities will enrich ideation workshops in co-design.
