I've been looking for a mobile for my son who, at 16 months, screams with delight every time an airplane flies overhead (though curiously not as enthusiastically when it's in Virgin colours
).
I am currently trawling through the list at
excite.com - I have seen a few possibles such as
this company in the Netherlands but the goal eludes me so far.
Will let you know if I get anywhere with this.
