Welcome to XLchem [v2]! a molecule rendering program. You start of with a nano quartz crystal. you can use the arrow keys to rotate it, W and Q to zoom in and out, and E to reset the zoom. Pressing B will toggle the BG color. Here's the formula for benzene: [v2]6C6H*1-2@1.5*2-3@1.5*3-4@1.5*4-5@1.5*5-6@1.5*6-1@1.5*1-7*2-8*3-9*4-10*5-11*6-12* Here's carbonic acid, shaped like a fighter ship: HOCOOHZZZZZZ*1-2*2-3*3-4*3-5*5-6*2-7*2-8*4-9*4-10*5-11*5-12* Or the simpler H2O, i.e. water: HOHZZ*1-2*2-3*2-4*2-5* Press space to enter a formula, it will sort the atoms out, gradually get them together, and then stop simulating it. you'll know when it's done when it jumps back to 30fps. Formula format: [You can now just use the editor: https://scratch.mit.edu/projects/53977538 ] The format this program expects is as follows: a list of elements and their amounts, and the links between them, with "@" followed by the bond order if it isn't a simple bond. i.e: H2O*1-3*2-3* "*" is used to separate the list of elements present from the links, the links from each other, and to mark the end. Elements go together in any order, in their correct symbol form, without spacing. Links are basically (number of an element)-(number of the other element), so 2-3 would tell it the second element is linked to the third. Elements will repel each other, unless linked, in which case they get closer until they're touching, no closer.

Second release, check the forums for more details: http://scratch.mit.edu/discuss/topic/55630/?page=1#post-469340 Updates: -More atoms -Double bonds, triple bonds, etc. -slight optimization (?) -green BG (finally, a green screen :P ) Known glitches: -molecules sometimes sink into themselves...
