I got sucked into a side project in recent couple of weeks as a side effect of ramping up on ReactJS. Maybe somebody will find this useful. Suggestions/comments welcome!

Thanks!
Stellar HD Account generator based on mnemonic.

That looks pretty awesome. You might want to change the name from Redshift though...which is a pretty well known Amazon AWS database product. (https://aws.amazon.com/redshift/)
Thanks! Yeah, it's probably OK for now. It's a tiny helper tool. There are probably hundreds of products named like this but I feel we should have priority being in "Stellar" ecosystem so all names "outer space" should be reserved for us ?
10 months later
? A new, refactored, thoroughly tested, well-documented, fresh 
?? version of our stellar hierarchical deterministic address library - redshift - just landed in npm.
You can go play with it via RunKit and restore some addresses or create new ones.
There is also a front-end that will let you generate mnemonics in 8 different languages or restore from those mnemonics to get your stellar account key-pair.
And as always, you can follow us on Twitter and follow our github.
Cheers!
Stellar Fox Team.
