When it comes to crowdfunding campaigns, it seems my grandmother was right: if something seems too good to be true, it probably is.When the Scribble pen launched on Kickstarter in August, it promised to sample any color on Earth and then either print in that color or splash it around on the screen of a tablet (depending on the version). However, two days after the launch, based on some concerns among backers and potential backers, Kickstarter stepped in and asked the makers of Scribble to provide a more detailed video within 24 hours showing exactly how the pen was supposed to work.
