They are cheating :-)

The laser and sensor aren't standard Lego parts. Still impressive.

Is HN allowing duplicate submissions now? I don't see a difference in the URLs for this and [1].

I am glad this is getting some attention. One of the authors is a former coworker of mine and told me about it a couple weeks ago.

The acrylic cases are backlit with blue LEDs...

This is just adorable. Now I feel less guilty about putting up LED lit fans in my computer.

someday I'm going to build a nuclear reactor out of legos just for the buzz

LEGO

Relax - no need to be rediculous or a pendant. It's obvious what is meant by "legos," particularly in context.

It may look like shouting, but the brand-name is upper-case singular. I was almost more surprised that the OP uses the name correctly, as the transliteration of LEGO to legos is as common in North American English as Los Angeles is to the awful 'Los Angelease' in the typical British pronunciation.

The vernacular continues to hoover up brand names.

He's just trying to put a band-aid on the problem.

More like brand-aid?

I don't think people outside the company commonly write it as LEGO even in its native Denmark. Just spot-checking at one of the major newspapers: https://encrypted.google.com/search?q=site%3Apolitiken.dk%20...

Given that Lego is not an acronym (it's a mangled contraction), there's no particular rule to say that this one brand name gets special treatment. For example, we don't use CHANEL for Chanel, despite their trademark always being in capitals.

I'm not sure that North American English speakers should be throwing stones about the pronunciation of El Pueblo de Nuestra Señora la Reina de los Ángeles del Río de Porciúncula. ;)

Not quite what you mean, but this is still fun. JK Brickworks on a LEGO particle accelerator [ http://jkbrickworks.com/lego-particle-accelerator/ ], the LEGO particle being accelerated here is a LEGO soccer ball.

What is this "new SI" ? New to the US, Liberia and Birma perhaps..
