We used the deep learning style transfer to stylize pictures/drawings with Van Gogh Style. Here's the best one that turned out great (out of 10,000 pictures we styled, this is what everyone loves unanimously) https://www.amazon.com/dp/B07831NQJ7
Then we turn them into paint by numbers kit. https://www.amazon.com/dp/B07H2VDKM1
Apparently the paint is classified as Hazmat, and it took us 6 month to get this thing approved to sell on Amazon. Which kind of killed the idea, as we had to pivot and do other things in order to stay afloat.
I always wanted to learn to paint, but I don't know where to start. I know the first few paintings is going to be ugly, and I don't really want to paint apples and oranges to learn. So this whole startup idea is to make it easy and fun to get started on painting and get the momentum going, because what you paint is idea(picture) created by you. And the painting methodology is simply filling in numbers with colors.
I hope one day I have the time to get back to this. I really believe in this idea.
