Me and MasterMind555 have been quietly making a Powder Toy remake in Java and are now ready to announce it.
This is...

Java Powder!

It is entirely made in Java(with a C# launcher), has a forum(temporary), a Twitter(@JavaPowder) and the game is almost ready for its first beta release(Some bugs to fix and saving to add)
It currently has 4 elements, one of them being Electricity(not working great atm)
Yes, yes, you might think it is bad because of all the less elements, but Powder Toy is at version 52 and we are at 0.2 D:
Some screenshots of the current beta(and some visible bugs D:) :
1. The launcher

2. The main window

3. The control window

4. The elements(blue is supposed to be water, light grey is supposed to be a gas D:)


Current version: 0.3 alpha
Next release version: 0.5 beta
Changelog: http://pastebin.com/G1X1qcXC

Any questions will be answered.
