Shining Star LED

Here I dedicated to my fan. How make a shining star. This scheme suitable for electro beginner, when i teen-age, a create some running, chasing 10 LED use IC 4017. it's work. and i become actdictated. next project are bicycle LED, Horse LED ( a horse? yes, feet, head, tail made from LED, wired together, lovely put on my desk).

The design of star LED is each feet (5 or 6) can light sequentially. need more than one IC 4017, or you just link in series or 5 LED. need TR to pull more power (20mA x 5 LED) better if you use Blue LED, but it's more expensive than green LED. (double price)
not yet to take pic, how about your design?
