Powershell, 77 bytes
I must say I thought this would be easier with PowerShell, but it's quite hard to create something more condense than this.
$a=@("/","\");"$(1..6|%{1..3|%{1..6|%{$a[$b]*5;$a[!$b]*5};"
rn"}; $b=!$b})"
More readable:
$a=@("/","\")
"$(1..6|%{
1..3|%{
1..6|%{
$a[$b]*5
$a[!$b]*5
}
"`r`n"}
$b=!$b})"
I'm using the index numbers of the array in order to decide whether I should put \
or /
and between every loop I simply toggle the variable.
