Cross (X) Track Projection.
In that case I think my answer would be "yes I have seen the
projectors, because they often get in the way of other signage - but I
don't recall ever seeing whatever it is that they are projecting.

Advertising on the underground is becoming more digital, and I've
noticed a few stations with LCD screens on each side of the escalators.

I have to say that I find them unwatchable as the images move before I
can concentrate on them so I tend to look away.

At least with the regular paper posters if one catches my eye as I pass,
I may find another further up or down the escalator. Not all catch my
eye.

In all I don't think it's a positive development, at least for
advertisers, as they're probably paying huge premiums to make and
display electronic adverts that end up being largely ignored.

I didn't understand what XTP was either. I try and ignore those too,
when I see them.
