Ephemeral spaces and relational aesthetics are powerful means of communication and connection, where ideas can be embodied and memories generated.   
 
Carefully developed concepts transmitted through unexpected media relations (such as light, sound, digital/physical elements) while addressing different senses simultaneously, may have a profound impact, This may also include participatory or interactive systems.
 
Edible light installations, sensorial giveaway kits, and spaces that scream colours are some examples of what can be done.  Meaningful experiences stay.
