serial port method.
Get a pic microcontroler with built in serial port and a DtoA converter. Connect each (1 red, 1 blue, 1 green) to its own individual DtoA output (with a current limit resisor picked so 5V results in full led brightness ((5V-VfLED)/(IledCONT)= R). next hook your serial port to the pic via a RS232 to TTL converter (MAX232 is a good choice). write some simple code to read 3 values from the serial port and dump them to the DtoA reg (too long to post here send me Email for help or look at the ap notes on microchips web sight) and tada you have a serial controled glowing ball....
10baseT ethernet (UDP/IP) method.
go to http://home.att.net/~wireb/niode/niode/index.html
build a niode and hook the led to that. I am currently working on new commands to allow the DtoA converter to work for a use similar to this (controling fiber optic lights in celing tiles). A lot more work but you would be able to control it from anywhere in the world that can send UDP trafic to it.
IBMs policy is 1.) pasword must be >= 8 char 2.) must contain at least one letter (A-Z) 3.) must contain at least one numeral or sym (1-$) 4.) cannot contain any parts of any past passwords
IE "stop4me0" == "this1stop" and is not allowed 5.) cannot "recycle" passwords (system rembers all old passwords and cannot reuse any of them) 6.) user must change passwords every 6 months
about the only thing they have not done is force users to have different paswords on evey system they are on.
The thing that pisses me off the most about these rules is not the rules but more the lack of a update system. Every 6 months I spend apx 2 days just trying to find all the diffent systems I have accounts on. I wish there was a tool that just listed all the systems with your useid on them and had a link to where/how to change them....
niode stands for Network Input Output Device for Ethernet. Basily you have a 10baseT, 10base2, or 10base5 port on one side and a DIDO port on the other. You communicate to it via a standard ethernet network and UDP packets. In fact If you need wireless just add a wireless ethernet converter ($$$) and its wireless. Multiples no problem just have to give each unit its own IP address... Currently I have most of the basic functions done (ethernet config, ARP, PING, and basic UDP packet handling) just need to finish up the code that takes the data from the packets and does some thing usefull. About 3 more good days of work and it could be done but need to actual work on it... URL is http://members.home.net/wireb/niode/niode/index.ht ml best of all they will be cheap. I am expecing the part cost to be under $50 for everything when done. Yes I know the page is not up to date (will get to it some day too busy working on the project right now.)

Post some photos. Have seen some real knots in the past (personal favorites are tar/cloth on glass).

Ok 2 not so easy ways to do it...

Some people do not use NIC with MAC address (dial up users) so that part of the spec must be optional.
