Free Invention du jour

Lego blocks with passive (battery free) wireless 3D location chips in each of them and maybe some fancy local receiver-locator that talks to your phone/pad.

Use cases…

1. When building to a pre-existing design one could get positive and negative alerts from your co-located phone/pad, subject to whether you are placing the block in the right place or not. Aided builds, so to speak.

2. When building something new, the design could automatically be fed into a Lego CAD for sharing and socialising.

Geez, it’s tiring…
