Hi 
No chance. 0.5 will never be made.
I greatly appreciate everyone’s enthusiasm for the project, I never expected people to be interacting with it 6 years later.
However nothing has changed since I archived the github repository 2 years ago, my involvement with this project is over. I encourage everyone to fork it on github and make it into something even greater and more popular.
I’m turning off all my notifications for these threads and it is my preference for these threads (this and Sketchbook v0.4 (three.js + cannon.js playground) ) to be archived, if possible. @Fyrestar @Mugen87 @prisoner849
I believe that discussions surrounding any related projects should be focused, productive and stand on their own, rather than my dead posts being brought up every 6 months with no input from me, the original poster.
Thank you to everyone commenting and wishing you the very best.
And thanks to Mr. Doob for Three.js of course!!
