I have to admit, I was a bit under-whelmed to learn the 'smart keychain' is basically a few addressable LEDs. Haven't Arduino and ras-pi had stuff like this for ages? A quick google search turns up tons of ras-pi stuff for kids, that seems more interesting...

The form factor looks interesting. Is this device easy to use? Is it compatible with Arduino? (I guess no, but it would be a good idea.) Does it has any sensors/buttons? We bought our daughter an Arduino kit when she was young, and she played with it for a while. It has a few sensors, like a photo resistor for light, buttons to press and IIRC a temperature sensor. We bough in the local store a 7-segment display and other small stuff that was not included. She made a few small projects, for example sensing the illumination and showing the number in 7-segment display.
