Raul, This has some good ideas. I would teach f before g . And I also
translated your ideas into my style as an alternative.
f=: 13 :' 5>: %:(*:i:y)+/ *:i:y'
f
5 >: [: %: ([: *: i:) +/ [: *: i:
g=: 13 :'y>:+/&.*:/~i:y'
g
] >: [: +/&.*:/~ i:
dmsk2=: 13 :'1j1 #"1(y*1+ ?($y)$#x){'' '',x'
dmsk2
1j1 #"1 (] * 1 + [: ? ([: $ ]) $ [: # [) { ' ' , [
'/|\o' dmsk2 g 5

The shamrock is very attractive!

It looks like 3/17/2012 12 am EST is in the past, so I dug up the solution I
wrote for this, and here it is:
rmsk=:2 :0
1j1 #"1 (' ',m) {~ n * 1 + ($n) ?@$ (#m)"_
)
gf=: '/|\o' rmsk (5>:+/&.*:/~i:5)
sham=: 'Oo' rmsk (5 >: <./(5 10, 13 5,:13 14) +/&.:*:@:-"1/ ,"0/~i.21)
Example use:
gf ''
\
\ o o o \ o /
| / o o \ \ o / |
o \ / \ o | | / /
/ / o | | / | \ |
\ o / o | o o \ o o \
/ o / / o | | \ \
| | o \ | | / / /
o o \ | o \ | o |
\ o o | / | /
/
sham ''
