Hello,
We are not really planning any such products at this time, but if you consider the fact that Tech Readouts can be used, basically, as coloring books, you could take the relatively low-cost approach of buying one (or more) of our Experimental TROs and printing off the image pages for your son's use as coloring pages. The benefit, of course, is that for one low purchase price, you have thirteen different units you can print (and he can color) over and over again.
Hopefully, that helps.
Thank you,
