I don't, but I run the same system configuration, so I can compile it on my computer, transfer it and run it.
Alternatively, if a compiler such as gcc is available, you could also run
# https seems to be broken on this website currently
wget http://www.daidouji.com/oneko/distfiles/oneko-1.2.sakura.5.tar.gz
tar -xf oneko-1.2.sakura.5.tar.gz
cd oneko-1.2.sakura.5/
gcc oneko.c -lX11 -lm -o oneko
./oneko &
cd ..
# remove all traces
rm -r oneko-1.2.sakura.5 oneko-1.2.sakura.5.tar.gz
so, to remind your coworkers that they should securely lock their computer, you download some software from http and run it on it?
