Oops! Sorry.
It never crossed my mind. Of course you wouldn't.

So my suggestion is a miss, then?

cliplipipp?

Yes! ghost is perfect. See how you explained it. "ghost" is the natural
term that you came with, and it explains very well the effect.

I was assuming a moving blur due to the multiple instance showed, not
realising it had to be explicitly repeated.

Go For ghost!

(Not to be confused with ghoti, which would be pronounced as fish.)

Could it be an option to allow multiple instances of the "blink" keyword?

blink 0.0 0.1
blink 0.5 0.6
...

Or maybe use an arbitrary number of two-valued vectors instead of just two 
numbers?

blink <0.0, 0.1>, <0.5, 0.6>, ...

Or something like a "time map"?

blink_map {
 [0.1 blink]
 [0.5 blink]
 [0.6 blink]
 ...
}

(this is assuming the object starts at time 0.0 as visible, then at 0.1 
becomes invisible, at 0.5 visible again, at 0.6 invisible again...)


As a name for the feature, it reminds me of the way different parts of a 
presentation are shown/hidden in the "beamer" package for LaTeX (used to 
create power-point-like PDF presentations). So I suggest:

only
time_only
time
time_domain
time_span
switch  (would it conflict with #switch ?)
exists

You sound like an Ulsterman.
And if you don't get that. Then it is more credit to you. ;-)

I already thought about that, but I guess for now the feature is useful 
enough as it is, so it's very low on my to do list.
