Guz,
Your new entries are AWESOME! We were wondering what happened to you! :) Glad to see you came roaring back. We REALLY like the "skyscraper" entries and particularly
#129. The "particle accelerator"
#128 is really slick...we don't know if it's quite there yet in terms of what we're looking for or not, but we really like it and its potential. Entry
#131 has a really nice nod to HVAC mechanical vents...if you can somehow work plumbing and electrical into that one too, you might have the winner! Haha! Good Stuff!
