Over the course of the last few months I've been doing a fresh rewrite of Project Macaw (based on phnx) in enyo 2. It is coming along very nicely at this point.
In case you are not familiar with Project Macaw (or it's predecessor phnx), it is a twitter client for webOS written in mojo. There is still a fairly large user base, and it is still actively maintained by myself and a few others.
The enyo rewrite is open source, and you can grab a copy at https://github.com/minego/macaw-enyo
Please read the README.md for instructions on building for various platforms. Right now it runs best as a chrome app (either old style or new style), or on Firefox OS. It also runs fairly well on android (using phone gap) and on BB10.
