Hi Daniel, On my blog I have posted a screenshot of a flowgraph that
scales an object by a randomly generated number every second. I guess
the most relevant part of the flowgraph to you is the Time:Timer node.
This node will output a count, ticking away at a specified period of
time, eg a period of 1 equals 1 second, which means in this case,
every second triggers a randomly generated number at which to scale
the wheelbarrow. And by leaving both the min and max values at 0 the
node will continuously tick away.
