Sometimes one clock just isn't enough. If you want to track the time in multiple locations without using an app or web site, this clever IKEA combo might do the trick.
EO Jackson at IKEA Hackers combined nine $1.49 Vackis clocks inside a $8.99 Ribba frame. While the original design has the time synced, you could also set different times on each clock (or row) to cover global time options. Just don't forget to switch the alarm off!
