I made some alterations became disgusted with it and am returning back to the design. The first picture is the current incarnation. I have the foot rest off right now because I am leaning towards something different. I'm also considering redoing the top, making it adjustable and possibly more circular in design. A bigger change is thinning the legs down from 2.25" to 1.5". Will see where it goes. The second picture was the direction I went in when I was fed-up with the design.
To answer some of the questions and comments.
George C: It depends a lot on the type of plywood. I've noticed a lot more designs, which are incorporating laminated birch plywood.
Joe Manus' multifunctional desk is what made me start thinking about trying it out on a project. I also plan to soften the edges during construction.
4DThinker: I was thinking a mixture of hand cutting and a template bit on a router, as well as a band saw and the spindle sander. And thank you for the advice.
rrich: It will be in a dry environment.
TonyM: Kids aren't an issue, but I do plan to soften the edges some.
