+# Bad Apple demo ![](app.png)
+
+"Bad Apple" is like "Hello World" for graphics system. So this is it
+for Bangle.js2. Watch have no speaker, so vibration motor is used,
+instead, to produce (pretty quiet) sound.
+
+Tools for preparing bad.araw and bad.vraw are in prep/ directory. Full
+3 minute demo should actually fit to the watch.
