What is this?

[James McDonald]

I just did ssh-keygen -t dsa -b 1024 and I get:


The key's randomart image is:
+--[ DSA 1024]----+
|                 |
|                 |
|                 |
|        .        |
|       oS.       |
|     .+ o..      |
|     =+o.=..    .|
|    . ++oo+ .. E.|
|    .o  .... .+.+|

What the heck does it mean?
