Laziness coefficient: high.

If I were a better person, I’d have wonders to show you thanks to the hours I’ve spent doodling in my Top Three Best Current Physics Toy Things, but I’m not, so I don’t. Instead, here they are for you to play with, so you can see if you can empty your laptop battery quicker than it takes to get you to get fired for never doing any work again ever:

OE Cake: impossibly flexible physics creation tool. Watch the videos on the site and do some YouTube trawling to get some sense of just how powerful it is, and how many crazy machines and explosions and cakes you can make with it. The moment your brain finally dissolves into an adoring whimper is the moment you realise you can drop-and-drag images files in and turn them into lumps of burning rubbery fuel. Handy cheat-sheet in the notes here.

Powder Game: the latest version of Hell Of Sand,  which makes you wonder why the world bothers having anything in it that isn’t fireworks, bubbles, C4, gunpowder or superballs.

Fantastic Contraption: so fantastic, it seems to have fallen over for now, but presumably it’ll be back. My brain has filed it as a cross between Braid and Crayon Physics, which is highly misleading, but will make you curious enough to play it so I’m sticking with it.
