This is a bit OT, but I've following the project for a couple of years and the product is just becoming available in the USA, hopefully elsewhere next year...
The Shaper Origin is a completely new concept in hand-held tools - it's a CNC router, in your hands - it handles pretty much any size of workpiece and is just a lovely concept (now a reality). X/Y & Z.
I'd really encourage you to have a look at the videos surrounding this, specifically how it works - the technology is awesome - the visual recognition work and maths is just great.
I have no interest, financial or otherwise, in this product as we can't yet get one in the UK (and they're currently 110VAC only), but it's a harbinger of things to come.
As soon as they are available here, I'll have one!
Warning: Not cheap. At all.
Cheers
Nick
