  • 5Mixer: Cityscape! At 170 chars I had it moving quickly, and with much, much better randomisation. To see the paralax work, multiply q=t*o by 10. I would have loved to have had a little car emoji too, but oh well, I'm still new. I've spent way too long trying to shorten this lol.

  • SpecialAgent: correction, q=t*o*9 works
  • lionleaf: If you change the dweet itself you can post directly and it becomes a remix. Post the moving one!
  • 5Mixer: Woah, thanks for the replies guys. I looked for ages and didn't spot those chars :) Remixed it moving faster.
