This is a fireworks Java applet having special features as follows; gradation(click a middle button), sound, a set piece of fireworks(optional strings), running fire(click a right button), and so on. Enjoy yourself!
- Mouse operations - Left button : pause Right button : running fire Middle button : change of gradation on/offThis background image is imaged as an aquatic display of fireworks.
You can change the image, message, font size, and so on.
- Hints for your setting - 1. Using a dark background image will visually twinkle more. 2. The average of shot interval is in proportion to the maximum shot interval(WAIT) and in inverse proportion to the maximum shot number(UMAX). 3. Increasing in the number of balls per a shot(TMAX) makes big fireworks. 4. A large width or a large height makes the running speed slower. 5. Turning off a gradation makes the running speed a little bit faster.
