Thank you Dunster for the link - which also says Pentagon Star so that is what I will call my quilt which is "Tim's Quilt" at present. In my pre-internet days of 1993, I struggled as single mother with young child and couldn't afford fabric so I played with my templates and drew numerous patterns with Irregular Pentagon (Complete Book of Patchwork & Quilting for Australia & New Zealand 1986) - my patterns include fish, scissors, frogs, aeroplanes etc embarking on tessellations, which I'd never heard of back then!!
I appreciate that more than one person can have the same idea even though we might be worlds apart.
