"Not my favorite"
Looking at this makes me think of two things. From a smaller (thumbnail) version, it looks like a close up of those lava cave monsters that Spock communed with in Star Trek. From the larger version, it reminds me of scabs on skin.
While an interesting experiment, not my favorite by far. Still one never knows when you start these things how they turn out.
And of course, the blue version in the pickle jar is my favorite of these. ;o)
