I actually missed your artifact since it looks like you never posted it in the main blog post round thread where it's suppose to be posted. Bummer! That means some of the other judges probably missed it too when we voted for that round.. I try to tell people to put it in the right place when I see that they didn't, but for some reason I didn't notice that you didn't put yours in the right place? 
Oh well, at the very least I am going to use your ladder in some form. Thanks for reminding me! I love the ladder idea.. And I think I have a good idea in regards to how to use it. :)
