The product copy on the Kickstarter campaign page is nonsense, targeting "ambitious designer[s}" using words and phrases like "freedom" and "your design journey." Yet the ruler sets, which run about USD $70, have been over 1,000% funded, with 25 days left in the campaign.
There is a lesson here for design entrepreneurs. Yuan Design Studio founder Im Ken originally provided lasercutting services for other designers. If I had to guess, I'd say the birth of this product came more from "What can I make with a lasercutter" than "What do people need that I can provide?"
I suppose I should be encouraged by the popularity of items like these, as it means perhaps more people are drawing; but the cynic in me suspects it's just more stuff to fill drawers with.
