[Theodores]

I found many of these creations to be remarkably similar to diatoms:

Also the concept of coloured sugar reminded me of the coloured sugar cubes my grandmother put out for tea with guests. These were proper bought ones and commonly available many decades ago but I have not seen them since.

Generally if someone has a taste for sugar (in tea) they really have no taste. So sugar sculptures as edible food items are going to be 'playing with food' to a certain extent, not that 'yummy' to most people. Maybe sculptures such as 'diatoms' is where this technology can excel rather than 'food'.
