leiqunniの日記： NeXTCubeは完全な立方体ではない

映画「Steave Jpbs (2015)」の台詞で、

00:41:21,361 --> 00:41:22,994
Why isn't it a perfect cube?

00:41:22,995 --> 00:41:25,631
- You've asked me before.
- I forget what it is.

00:41:27,267 --> 00:41:28,467
It's an optical anomaly.

00:41:28,468 --> 00:41:31,737
To the human eye, a perfect
cube doesn't look like a cube,

00:41:31,738 --> 00:41:34,273
so we made it roughly a millimeter
shorter than a foot on two sides.

00:41:34,274 --> 00:41:35,840
What's an anomaly?

00:41:35,841 --> 00:41:37,710
You've asked me that before too.

00:41:37,711 --> 00:41:40,312
I don't know why you keep doing that.

というやり取りがあるんだけど、
この錯視のことと、NeXTの公式文書記録があれば見たい。
30cmの立方体でなく、底面だけは29.9 x 29.9 cmということなんだろうか。
