Before I reinvent the wheel, I'd love to seek your wisdom.  I am looking for a way for students to drag their photos on a RULER-based mood meter.  The mood meter is four squares and students identify their current mood/emotional state by identifying a color.  In person, I would typically have students place a velcro-backed laminated photo on the square each day to share how they're doing when they enter class.  However, I'd like to have them do it on their devices to avoid touching the photos and the board.  Any suggestions for a tool that will allow me to do this?  I was thinking I could use Padlet, but it wouldn't really be the interface I'd like to show the square.  Any suggestions will be much appreciated.  Thanks!
