How about a start of a high level function: function bigbang() { $elementsNecessaryForBang = God::createElements(); // have to get it from somewhere, don't know how to get this just yet $particleSimulator = new ParticleSimulator($elementsNecessaryForBang); $particleSimulator->start(); // ... return $universe; } Oh, I forgot. We're writing this in plain MySQL? Don't know how to even start this... :) I guess this is a PHP List, so I guess it's safe to use PHP, no? Sorry for stealing the thread...
