I showed a Seder plate to a shop manager today. Great feedback, which underscored the value of letting people help create their own look.
For instance, the letters in the item locations are all rotated so that the PESACH is at the center. Many Seder plates have the labels parallel, so they all can be easily read from one place. When I’ve asked about this feature, I find that about 60% of people prefer the letters to line up with each other, and 40% prefer them to radiate from the center. With some customization interface, this could be determined as part of customizing a plate.
Custom carving to order caries more obvious value, and it could be more fun for me, too. I like making things specially for people who want them. It may soon be time engineer the user interface that enables selecting options, and quickly renders images with the particular selected collection of features.
