All free.<\/p>\n<p>The idea is that a series of small balls drops from the top of the screen, and you draw lines on the screen for the balls to bounce off of.  Each bounce makes a sound (with pitch affected by various factors).  The balls are influenced by gravity and air friction, which you can adjust. The result is a pretty, entertaining, noisy piece of art\/music\/fun.<\/p>\n<p>There are more instructions on the BallDroppings page.  Note that when you launch the app, your screen will go black; to draw lines, just click and drag.  You can also drag the endpoints of lines you've already drawn, and you can delete existing lines.  You can even save a configuration and restore it later, though there's only one save file and getting to it on the Mac (to make a copy of, or to share with others) is a little tricky.<\/p>\n<p>Anyway, it's cool, it's fun, it's pretty, and if you're really good\/careful it may even be musical.<\/p>\n<p>One thing I don't understand about it is the bounce algorithm--it's not the usual \"angle of incidence equals angle of reflection\" thing, so it can be a little hard to predict which way a ball will bounce. But that doesn't really detract from the fun.<\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>Scott introduced me to a nifty software toy: BallDroppings, available for Mac, Windows, and mobile phones, plus a Java version&#8230;.<\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[62,58,7],"tags":[],"class_list":["post-3297","post","type-post","status-publish","format-standard","hentry","category-gadgets","category-games","category-music"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.kith.org\/jed\/wp-json\/wp\/v2\/posts\/3297","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.kith.org\/jed\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.kith.org\/jed\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.kith.org\/jed\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.kith.org\/jed\/wp-json\/wp\/v2\/comments?post=3297"}],"version-history":[{"count":0,"href":"https:\/\/www.kith.org\/jed\/wp-json\/wp\/v2\/posts\/3297\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.kith.org\/jed\/wp-json\/wp\/v2\/media?parent=3297"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.kith.org\/jed\/wp-json\/wp\/v2\/categories?post=3297"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.kith.org\/jed\/wp-json\/wp\/v2\/tags?post=3297"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
