Goal

The goal of TOY86 design: keep the thing down to size, while making the thing insteresting enough and at least as beautiful as the classical TOY.

1. down to size：因為目標是讓 cyy 採用為教材，所以規模不能太過龐大複雜。
2. insteresting enough：TOY86 所實作的功能必須有代表性，把整門課最精華的部份收納進去。
3. beauty：開始構思 TOY86 後，才真正感覺到 classical TOY 設計的協調美感。TOY86 的設計不能比 classical TOY 還差，否則怎麼能夠當示範教材呢？XD

這就是 TOY86 設計的主軸思維了。
