Either of you please email me with your backer number and I can refund you or turn what you paid into a donation to Médecins Sans Frontières if you are not happy.<p>I am very pleased with what is there so far, think it genuinely captures all the best bits in an accessible way. I am most proud of the Escher and Evaluator bits and associated projects.<p>I have lots more partially complete, feel I have a fair bit of momentum now and do still intend to make videos as I said in the update to backers, backers will see them first. I am genuinely sorry it has taken so long to get this out.<p>I think I was quite fair minded re: pricing etc during the kickstarter. I changed it from a sliding scale to allowing unlimited people taking the lowest amount (£20), then created a &#x27;pay what you can&#x27; tier and invited people to switch to it if they wished.<p>Best wishes, 
Tom
