1. There is one inspirational book, it is called <em>
<a href="http://10print.org/">10 PRINT CHR$(205.5+RND(1)); : GOTO 10</a></em>. 
Its name in BASH can be written like this:

<pre> 
while true; do printf \\$(printf '%o' $[47+45*(RANDOM%2)]); done
</pre>

while true; do printf \\$(printf '%o' $[45+79*(RANDOM%2)]); done
 while true; do printf \\$(printf '%o' $[123+(RANDOM%4)]); done

A+=(140745122766848 140746759356416 140738707374080 140739778977792 140754249564160)
for i in ${A[@]};do echo "obase=2;ibase=10;$i"|bc;done|sed -e 's/1/ /;s/0/ /g;6i\ '

Yes, is not obvious what it is doing on first sight and reminds me

10. Utility dialog is used for textual widgets, if you need get
some free-time use following command:

for i in {0..100}; do echo $i | dialog --gauge "Upgrade in progess" 10	70 0; sleep 1; done
