"Trash" Stamps

I've been doing a lot of stamp carving lately and as a consequence, I've got lots of leftover rubber scraps.  I hate to waste it, so I make "trash" stamps: random little designs on the leftover scraps.

The first stamp is what I call a "really useful stamp."  It's a simple design -- nothing sexy, just a basic -- that you can play with and use in a number of graphic ways.

The second stamp is a repeating stamp.  When it's stamped repeatedly it makes a (mostly) seamless design.

The third stamp is the biggest and the most interesting, in my opinion.  It's a simple geometric design, but I think it has a lot of impact.

And here's a peek at everything all together:

What do you think?  Which stamp is your favorite?
