Design Concept

Dim Sum restaurant's kitchen may be different, but two things are always the same: steam everywhere and steam baskets stacking all over the place. This makes the lack of vertical space for chefs and they spend most of the time busily on the little preparing tables. 

When the customer knocks on a particular point on the table, this device on the chef side creates an image on an acrylic sheet out of steam to convey to the chef that he/she really appreciated the food. On a level below this, we have moving lotus floating on water which gives a glimpse of a traditional Chinese pond to relieve the stress of the chef after a long day's work.
