You could also play a bit with colors to suggest Doppler effects at 
approach and recession ;-)

I prefer the gifs too ;)
May I know which software you're using for them? Cool graphics. Provided 
it's not more complicated than Basic :-o

Nowadays things have to be fun, also in science and education. In my 
days you could have left me breathless when watching a program like 
Horizon (but our national versions admittedly) or listening to an 
inspired teacher. Now it has to be Games and Fun apps.
I'd have preferred to see MIT come up with breathtaking interactive 
explanatory demos of what's going on with relativistic phenomena, with 
good graphics but also with precise information, and without the "ludic" 
obsession.

That too is interesting meseems, in contrast with the former...

I think it is interesting and important to distinguish, evaluate and 
name the "apparent" (seen) lengths and velocities, and compare them with 
rest and Lorentz values, as I do in my pages. I haven't seen much of 
that elsewhere yet...
