# Block Rocket

A small toy-brick rocket: two grey nozzle bricks, red fins, a dark band, a white hull, a window and a red nose. A finished model of 9 toy bricks in one block: the brick list is fixed, so nothing needs writing out; it is the motion_bricks canvas with that list filled in, and every motion_bricks setting that does not name bricks works here the same way. Bricks drop into place in build order as p goes 0 to 1 and the model turns with the second dial (--s). Standalone it shows the finished model. Known limit, each brick canvas holds two WebGL contexts and a page allows about 16, so keep to about 7 brick canvases per page. Not affiliated with or endorsed by the LEGO Group.
