Box can be made from any available material i.e. wooden boards, MDF or plywood.
I had some MDF sheets in my scrap container so I've build simple frame from narrow panels of 1/2" MDF.
Before joining pieces together I've applied some carpenter's glue to matching surfaces. Glue fills gaps and add extra strength to joint.
All parts fastened with 1" wooden screws. To avoid material splitting I've drilled 1/8" pilot holes for screws and made countersinks.
Front and back panels are made from 1/4" MDF and attached to frame with glue and screws. Wooden putty can be applied over top of screw heads to make surface even and smooth.
|It's a good habit to keep scrap material just in case.|

Window grid physically isolates LEDs, eliminates color mixing, forms nice illuminated dots and prevents front sheet of veneer from flexing inward. For better contrast grid is painted black.
Window frame is mounted flush with front surface and secured with hot glue.
I've chosen transparent maple veneer to cover front panel. For sides and top I've decided to use dark walnut veneer so it would make nice contrast with face panel. Back and bottom panels are hidden from observer so I've just painted them black.
Veneer application is pretty simple. Veneer piece should be cut slightly larger than area to which veneer is being applied. It can be glued with the same carpenter's glue or similar adhesive suitable for wooden material.
Excess of glue and accidental drips can be easily cleaned with damped cloth. After glue has dried, extra material around edges should be cut with x-acto knife (Caution, it's very sharp!). Corners can be sanded with fine sandpaper. As any other wooden material veneer can be stained, finished and sealed.

|Pretty transparent, eh?|
Two tactile switches are installed on a small PCB. Two pieces of wooden 1/4" dowel are used to transmit force to button's top. Button assembly and power jack are mounted on a back panel. As final touch I've installed self adhesive rubber feet onto bottom panel.

Sadly, still pictures cannot show beauty of clock performance. In real life it looks much better.
|It's still 17:35. LED pattern changes every second.|
