Worlds you can create with Hex

While walking to Uni this morning Edd and me though about how many words you could spell with only using Hex chars {a..f}. I was thinking about this all day so I sat down and wrote a little program that would solve this problem for me:
First we have to generate all possible char combination:
From http://ribalba.de/geek/proj/hexword/wordcreate.py

 1: #!/usr/bin/python
 2: 
 3: #We want to create all possible combinations out of these chars
 4: # a b c d e f ' '
 5: #Somehow '' is not handeld correct so we have to remove it later
 6: wl = ['a','b', 'c', 'd', 'e', 'f', ' ']
 7: out = []
 8: 
 9: def recLoop(txt):
10:     if len(txt) >= len(wl):
11:         #Add to list and remove space
12:         out.append(txt.replace(' ',''))
13:     else:
14:         for i in set(wl):
15:             recLoop(txt + i)
16: 
17: #Start the recursion
18: recLoop("")
19: 
20: #So we remove duplicates
21: outset = set(out)
22: 
23: #And print
24: for w in set (outset):
25:     print w

The output file can be found here : http://ribalba.de/geek/proj/hexword/outfile this file has 335923 lines and is 2.5M big. So now we have to find out how many words are actually 'real' English words. To make it easy I just used aspell and some perl.
Source can be found here: http://ribalba.de/geek/proj/hexword/findwords

 1: #!/usr/bin/perl
 2: 
 3: use Text::Aspell;
 4: 
 5: my $speller = Text::Aspell->new;
 6: 
 7: die unless $speller;
 8: 
 9: # Set some options
10: $speller->set_option('sug-mode','fast');
11: $speller->set_option('clean-words','true');
12: $speller->set_option('ignore-case','true');
13: 
14: open FILE, "outfile" or die $!;
15: while (my $line = <FILE>) {
16:     chomp $line;
17:     # check a word
18:     if( $speller->check($line)) {
19:         print $line . "\n";
20:     }
21: 
22: }

And this outputs us a nice list of all the words you can spell in English with the Hex chars, see here: http://ribalba.de/geek/proj/hexword/hexwords
There are some freaky words there.
