T-shirt

[kenjihiranabe]

Hello guys,
I am a Japanese co-translator of "Linear Algebra for Everyone", and also a big fan of 18.06.
Last year, I made a T-shirt for fun. I'm not sure if this is an appropriate place to post, but I'd like to give this away to the staff around Prof. Strang.. what do you think ?

Here's a list of my contribution around 18.06, included in the professor's book site:
