The `alt2` is only necessary if you wish to compile the deobfuscated version but
it is equivalent in function to the original entry, [endoh1.c](endoh1.c).
In the `alt` versions a default time of 10 seconds is set as an alarm so that
one can more easily go through the list of files to see them all in succession

by the author, [Yusuke](#yusuke), at the request of the judges.
and also the gravity factor, the pressure factor and the viscosity factor as
well as an alarm that lets one run it in a loop without having to hit
ctrl-c/intr in between (the alarm can be disabled, however). The two different
versions is because there are two versions: the original and the colour version
added by the author, [Yusuke](#yusuke), at the request of the judges.
Cody also added the [try.alt.sh](2012/endoh1/try.alt.sh) script compiles the alt
code in two ways, one with setting the gravity factor to `I` and another with
the default, and which is run on the source file and each of the text files
supplied by the author. This code has an alarm set at 10 seconds so that one
need not hit ctrl-c/intr in between .. say to make it more fluid :-)

de-obfuscated version.
