Its got to be said!

The allegedly "Roman" Lituus looks remarkably like the Swedish NÃverlur http://files.reseguiden.se/files/0/rg_738300_m600.jpg. I remember David Munrow demonstrating something like it in his Early Music TV programme back in the mid-70s. It sounds very difficult to keep in pitch and I'd suggest that a Renaissance Cornett (perhaps even a Lysard, but not a Serpent) would be a more appropriate instrument for the performance.

Conjectural instruments like the Lituus aren't really worth the effort.

Really, I completely despise folk like you who have nothing better to do with your time than craft delusional "Christmas Greetings" to send to your less artistic/creative/self-important acquaintances. Of course, in times past the cretinous, badly photocopied "Christmas Letter" or "Roundrobin" was equally abhorrent, but at least that could be seen for what it was and disposed of accordingly.

Do you really think your recipients are going to wade through 512Mb of computer dross, just because you sent it? Or that it'd get more than one play before getting reformatted and used for something more useful?

Here's a suggestion that would generate a bit more seasonal cheer.

Buy a big bundle of high quality Christmas cards supporting the charity (or charities) of your choice. Write an individual, unique heart-felt greeting in each one and post them in time for the last week before Christmas. Then the recipients can pin them up and have a colourful reminder of your regards throughout the Christmas season, rather than a few minutes of irritation.

As for the USB sticks, why not enclose them as an unencumbered gift to those who might have a use for them. Or donate then to a worthy cause.

Someone else posted an example from the 1950s, but the "concept" goes back a lot further than that. Taking a cue from the doped linen aircraft fuselages of the early years of flying, various car manufacturers used a similar procedure to produce car bodies that were light and protected the passengers from the weather. These were mainly used for both mass-market sports cars and their more bespoke brethren.

BMW have just produced a contemporary version of this idea.
