Aiden would absolutely love this! I know several kids (boys and girls) that would enjoy this as a STEM introduction. Perhaps that's because here you can't get SNAP circuits etc. But it would be so cool to have this!
WRT gender toys - I agree that it comes from previous generations. And it's exacerbated by society too. I try and counter this by allowing my boys to play with whatever - they have dolls, brooms, toy tea sets as well as lego, science equipment and toy cars. They can choose their own colours to wear - although I admit they do not own anything pink simply because I cannot stand the colour. I refused to wear it from about the age of 9 onwards, although thank heavens from childhood photos I see I was mainly in reds and blues.
hving said that both my two oldest boy went through stages where they emphatically declared pink as their favourite colour. (And no, they were not listening to Prince/Symbol at the time)
