Introduction and Christmas light projects

Hi all
My name is Andrew.  I am quite interested in writing programs - which I have done a fair bit of through writing programs for robots using graphical programming, C and basic.  I have moved from robots to modifying Christmas lights and getting a picaxe chip programmed with basic to control them.  Here's a video of what this does:
This year I am using a different chip - the Atmel tiny programmed with C, to control a bus of 74HC4094N's (made by Phillips or NXP) using clock pulse and data wires to transmit the signal along.  To see how the 74HC's do this, visit the NXP website and check out the datasheets available for the 74HC.
