An inter dimensional portal only involves cutting holes in time and space and gets you at least another 4.362 cubic meters of space in the van with no extra fees for awnings.
I have literally just finished watching 12 Monkeys on the iPlayer... I think you should be careful that you don’t end up looking over his shoulder through inter dimensional transcendence whilst your 8 year old self looks on.
Nope ... It has already wormholed it's way into more than one parallel universe, including soups for example, so unless you wish to be caught forever in a time space vortex I suggest reading elsewhere! I'm just going to build my designs by the way and wait for others to pass judgement
Sorry, no, as i'm still tweaking before making ... As James Dyson might say, "I like designing in a vacuum"
