Hello dear friend! It's so nice to hear from you:)! I am super tickled that you gave me a link to peruse, as I hadn't heard of that particular tool, and holy circuits am I ever going to snag one or two for the children to experiment with. Um, I might mess around with the m:b a bit too, it's looks so cool, I'm going to show the kids the simulator tomorrow during tech time! Thank you:)
