Dancing Lights

This is a circuit in which the six leds blink in a pattern to make this circuit you need
1] transistor-bc148 or bc548 -2
2] capacitor-10 uf-2
3] resistors-47k ohm-4
4] battery
5] led-6  -3 green 3 red
6] pref board
i made this circuit from this book

you can pin the circuit to your pocket and see the charming colours.
i will soon post the circuit digram.
