After much puzzlement and swearing, I managed to get a mostly functional rocketpack to stream flaming particles out the back whenever I'm flying around. I think I know of a better way of doing it, so I might try that instead. But it looks pretty funky - I'll take a snapshot at some point so I can post it up on here.
Next thing to work on, is a flapping white Biggles scarf I think.
I also made an actual "friend". He showed me where I could get a load of free stuff, so I should be able to make all kinds of shiny toys now.
