Adjustable Color-temperature Desk Lamp

Do you actually mean T9 (the predictive one?) that would be pretty cool :)

There's a phone-style text entry thing for the morse code texter too. It's fun to see the different way of implementing it... It never occurred to me not to use a lookup table - I'm really not sure which way ends up more efficient :)

That kind of thing would make quite a good module though. I was also wondering about some kind of menu library (a scrollable list with simple up/down to select) that might save people a bit of work... It looks like yours does a bunch of other stuff though.
