ring the bell and win a prize

One of the favourite attractions at fair-grounds. has always been some variation of `bash-the-btock-with-a-mallet`. Originally, this was a purely mechanical device, although of recent years technology has advanced to the stage where no self-respecting fair-ground attraction is complete, without a dazzling display of flashing lights. However, electronics have now progressed to the point where a portable version is possible - suitable for desk,top use.
