As far as homegrown gifts go, this one rocks. Kids love lights, letters and switches. Put them all together and you get this cool toy made by Instructables author henlij.
henlij made this using about 50 LEDs, a voltage regulator, a power source from the junk bin, a power jack, wire, a scrap piece of oak and various switches. henlij made a simple template for LED placement in photoshop, drilled the pattern, planned a circuit, got out the soldering iron then put everything together.
