It’s rubbish!! :p
The irony of making something, rendering it and putting it on youtube means that as soon as you see it ‘working’ you see all the reasons why it won’t work. I guess this is what people don’t realise, you have to make something first to break it, then you take what you learn and apply it to the next version, and so on. That beautiful thing you just bought was remade 20 times and you think it looks so stylish and simple that it just sprang fully formed from someone’s head :p Oh, if only you knew the pain :p
Time to break it again!
