* More animations with generalized code to display them. * The hostname will now include a unique id of the ESP. * Effect can now be restricted to a smaller "window". * Clock is now BigClock, SmallClock is now Clock. * Clock shows the time as well as the sinematrix effect. Closes #8. * If the loop takes too long too often, the ESP will automatically be rebooted. Closes #12. * The text drawing methods are now much more generalized. #5.
