AND ... WE’RE BACK!
Since that night, the RoboSpinArt
machines have been a staple at Robot
Group events. We even had one of
them up and running during Maker
Faire Austin (Figure 24). The folks at
First Night were also very happy with
the RoboSpinArt performance. In fact,
they’ve booked us for a return engagement! At this year’s First Night Austin,
our two RoboSpinArt machines will
flank The Ponginator (see Nuts & Volts
December ‘07) which will be making
its inaugural outdoor appearance. We
plan to have the strobe light function
and the ink jet gantries added to the
RoboSpinArt machines by then so, if
you’re in Austin on December 31,
2007, feel free to come by and make
some RoboSpinArt with us! NV
