over the next few little whiles I hope to be sharing some of my experience at the OTA/Encyclomedia conference. If you have not been following the progress on Twitter do a search for #OTAEM15 to see lots and lots and lots of great information.
One of the coolio things I saw were the OzoBots (http://www.ozobot.com/). These neat little programmable robots follow basic commands. Draw a colored path and they follow it. Great for science, math, and art.
