Some quick sketches for not only black and white t-shirts:

And another one with musical instruments (inspired by that video)

my favourite is the musical one, when can it be ordered? other colors will be available also?

@szipucsu or the UK guys: Is that to necessary there on the green T-shirt?

Yes. Words can contain mistakes.  I just wrote the first things that came to my mind.


Thanks Bruce.

my favourite is the musical one, when can it be ordered?

You mean, the instrument, when can it be ordered? I would really buy a guitar like this but we would need some software, e.g. to set ring modulation and filter with the function keys to get the strings change sound. However it would be a pity to stick strings on a real Enterprise. We should change the box of the Enterprise which would be irreversible.

Cool idea, nice execution. However, if it were me I wouldn't have put that "and" into the footer.

I agree it sounds better without the "and", but is nor actually wrong.

If you are going to say "precautions" I think you really need to say what kind of precautions. As well as "safety" precautions, you could take "security" precautions to stop your T-shirt being stolen, "laundry" precautions to stop your T-shirt  shrinking etc. Taking "fashion" precautions probably rules out wearing the T-shirt !

You could say "...safety precautions and security precautions", or just "...safety and security precautions", so "...safety and precautions" sounds like there is word missing. But I don't think it is actually wrong, it just sounds a bit odd.

Also, the phrase "safety precautions" is so commonly used that any variation sounds odd anyway.

I think I need a "taking all unnecessary grammar precautions" T-shirt!
