Hi, I recently started with jQuery/javascript. I cannott figure out how I can create animation threads, e.g. constantly twinkling start, falling snowflakes, independent of any mouse/key event, using jQuery.. I just tried fadeIn & fadOut in a loop to display images on the background and it works but it blocks the browser UI so I cannot click the menus with the mouse until the loop is finished. Any hints will be helpful! Thank you!
