How can make a 10 or more LED flesher?

Actually I want to make LED multiple flasher by using 555-timer in my project board....
How can I make this???
The LED should flash alternatively.........
At first I want to make 10 LED flasher..........
After that I would try more than 10.......

A 55 timer will allow you to build a circuit that will control 2 groups of LEDs flashing. Alternating back and forth as to which group is on. If you use a 556 timer you can get 4 groups of LEDs flashing back and forth. Each group pair can flash at a different speed. A simple web or site search will yield a great many projects that make LED flashers from a 555 or 556 timer.
