I spent a ton of time, money and effort to build a project as a gift,

I could easily have purchased for less and probably a much better product. However, I don't think it would have had the same impact for the recipient, and myself.
So yes, could be purchased, but this project is an awesome combination of modules, code, and effort, with an awesome result. Plus the knowledge bomb that was set off is invaluable to many.
Thanks for sharing this project!!!!!
