Interactive Stuff

All the best stuff, that you can also interact with in some way!

Hey there! I’m Jeff. Since 2012, exactly as planned from day one, I have made zero profit from this site. We operate entirely on donations and your feedback because I firmly believe that learning should be accessible with as few hindrances as possible. If you’d like to support me, I have three different ways: 
 
Amazon Wish List for physical stuff, PayPal for donations, and Steam for Jeff's downtime.
 
Anything donated through PayPal pays the bills, with excess funds getting donated. 
Anything bought for us via Amazon, where applicable, sees the old stuff get donated or recycled.
Steam donations are our form of "greed and profit". Those are all mine 😉

Education should be free and available to anyone wanting to learn, with minimal interference. This is why you'll never see any revenue generating ads here.

We attempt to operate similar to a non-profit, and will utilize free resources before premium services, where applicable. Contact Jeff for further details.
