Detroit gets colder - and colder as we brace for one of natures more unpleasant seasons. I've completed my show and alas, folks don't have the enormous walls that my works require, so my show was a financial bust, tho' I got a considerable amount of spin-off interest. Sometimes that leads to financial survival.

I have some questions that I suspect is more in your line of expertise. For the time being I want to keep the idea under wraps, so mum's the word if you could. 
For my next art project (for want of a better phrase) I want to treat the galaxy as if it were the ultimate in archival hard drive storage informational storage.

Advantages of such a storage method are obvious when you think about it.
The information will only travel the speed of light. If the information was fired at the center of the galaxy (an obvious direction, for reasons I'll address in a minute) it would take the information over 50,000 years to reach the central Milky Way core.
What do you think the chances are that mankind will obtain the ability to circumvent light speed over the next 50,000 years?
If a human civilization in the far future were to study electronic archeology, they might start looking for information broadcast in the past. If they thought someone might intentionally have left information, they'd look towards the center of the galaxy, because it is a pretty common reference point. The north and south poles would not do, as 'true' North/South changes over a 22,000 year period.  One of the obvious places they'd look would be towards the center of the galaxy.
There is the added advantage of directing the broadcast at the Galactic center, in that if Mankind becomes extinct, there is an outside chance that some other species might pick up the broadcast.

First question is, can it be done?
Consider your answer in the framework of the resources available to the average Joe; part time garage science kinda stuff.
What would be the best way to send a message into space? (What bandwidth would make most sense? VHF? UHF?A tight beam of some sort?)
The parameters of the experiment is that you want to keep the broadcast as concentrated as possible, with the idea of longitivity during a long period of light travel through space.

If you've got a moment, let me know your thoughts.

Best,

Stephen
P.S.; I thought it would be cool to start with: Webster's dictionary, The Britannica, stream the human genome project and the human chromosome project out to the stars.
