Train Ceiling as Info Screen?

I want a navigation screen on a train that shows the exact location where the train is, not just “It’s now between station A and station B”.
It should also be seen clearly from almost everywhere even if the train is crowded. (In Tokyo it’s almost impossible for a stranger to know where she is on a crowded train if she misses one announcement.)
Is it the ceiling that is the most visible?

By the way, I’m now designing the calendar wallpaper for this month. Sorry for being late!

3D Image Display and its potential

If there were a 3D display, even a very small one, it would be a lot of fun. The real object’s image could be easily and clearly seen from any angle, and what else has been difficult to be displayed with our conventional monitors could be done as a matter of course.
So, here’s my ideas of what could be done if I had an external small 3D display:

1) photo slide show: mac-like cool screen saver would be nice

2) calendar: good to have aside of my iMac when working ’cause it’s not distractive but helpful. Being able to pick a theme like ocean, forest, etc. would be cool.

3) Google Earth: I just can’t wait to see the 3D building images moving! You have the real earth image in the box!

4) 3D applications: could be handled much more easily.

Maybe it would be also possible to display a holographic image of a person you’re talking to on the phone.
What do you think? Give me other ideas.
