          @Humus @csk hmm, maybe turn it into an awareness-building game (a la tower defense games) where you must fend-off hackers trying to topple the whole tower over and whack knowledge into capitalists'/politicians' heads that treat the ecosystem as a black-box; boss level: secure funding without caving into three-letter agencies pressuring the dev to sneak vulnerabilities.

                @csk Sometimes I wonder if this isn't the right solution to the software problem.

                      @robinhouston Yeah, it's really making the rounds! I must tip my hat to the people who came over to show their earlier demos of the same idea -- it really was hard to believe that nobody had thought to do this before.

                          @csk So you're saying if you shove aside the random person in Nebraska the architecture simplifies itself to something with fewer layers? 😆

                                    @csk Register the mousemove handler on the window object, then you will get the events even when the mouse moves out of the window/frame while dragging.

                                    @bloody_albatross If we're talking about improving the code, then I'd be more interested in the question of how to get a stable tower to stand up in a physics sim without bouncing all over the place and collapsing spontaneously. In this demo I use a cheap hack of freezing all the blocks until you actually click on one of them. Presumably it's really hard to get this working correctly (cc @topher_batty)

                                      @csk i like how there seems to be no friction and despite what block you klick, after some duration everything crumbles, even if you do not move the cursor while klicking.

                                        @csk @topher_batty I feel like that is basically what all games do anyway. Also saves CPU.
