Andrew,
You made the comment "I will one day make something like this".  Take
it from a guy that got smacked with age you need to get on with the
want to do list while still working on the must do list.  Time and age
and physical problems get in the way of doing those neat projects much
sooner than you can ever imagine.  Don't wait, just do it.
Happy Easter to all!
