What I’ve found is that artists now commonly use devices that actually place pressure against the artist’s hand to create a better feel while sculpting CG models. This is what I’m talking about:
What I’ve been thinking is that creating a script that allows an artist to connect Blender’s Sculpt Mode tools to this type of device could add up to the productivity. Just a humble idea if anyone is interested, that’s all.
You need to sponsor one of those devices to a developer and find out if the API of the device is compatible with Blender. I recall there were licensing issues with some devices. Good luck!
Here’s another one… this one should be going for around $150 once it’s released
